While there are many examples of nematic phases in a wide range of contexts, such as in liquid crystals, complex oxides, and superconductors, of particular interest is the magnetic analogue, where the spin, charge, and orbital degrees of freedom of the electron are intertwined. The difficulty of spin nematics is the unambiguous realization and characterization of the phase. Here we present an entirely new type of magnetic nematic phase, which replaces the basis of individual spins with magnetic helices. The helical basis allows for the direct measurement of the order parameters with soft X-ray scattering and a thorough characterization of the nematic phase and its thermodynamic transitions. We discover two distinct nematic phases with unique spatio-temporal correlation signatures. Using coherent X-ray methods, we find that near the phase boundary between the two nematic phases, fluctuations coexist on the timescale of both seconds and sub-nanoseconds. Additionally, we have determined that the fluctuations occur simultaneously with a reorientation of the magnetic helices, indicating that there is spontaneous symmetry breaking and new degrees of freedom become available. Our results provide a novel framework for characterizing exotic phases and the phenomena presented can be mapped onto a broad class of physical systems. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2404.13212v1-abstract-full').style.display = 'none'; document.getElementById('2404.13212v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 April, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2310.07948">arXiv:2310.07948</a> <span> [<a href="https://arxiv.org/pdf/2310.07948">pdf</a>, <a href="https://arxiv.org/format/2310.07948">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Strongly Correlated Electrons">cond-mat.str-el</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> 3D Heisenberg universality in the Van der Waals antiferromagnet NiPS$_3$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Plumley%2C+R">Rajan Plumley</a>, <a href="/search/cond-mat?searchtype=author&query=Mardanya%2C+S">Sougata Mardanya</a>, <a href="/search/cond-mat?searchtype=author&query=Peng%2C+C">Cheng Peng</a>, <a href="/search/cond-mat?searchtype=author&query=Nokelainen%2C+J">Johannes Nokelainen</a>, <a href="/search/cond-mat?searchtype=author&query=Assefa%2C+T">Tadesse Assefa</a>, <a href="/search/cond-mat?searchtype=author&query=Shen%2C+L">Lingjia Shen</a>, <a href="/search/cond-mat?searchtype=author&query=Burdet%2C+N">Nicholas Burdet</a>, <a href="/search/cond-mat?searchtype=author&query=Porter%2C+Z">Zach Porter</a>, <a href="/search/cond-mat?searchtype=author&query=Petsch%2C+A">Alexander Petsch</a>, <a href="/search/cond-mat?searchtype=author&query=Israelski%2C+A">Aidan Israelski</a>, <a href="/search/cond-mat?searchtype=author&query=Chen%2C+H">Hongwei Chen</a>, <a href="/search/cond-mat?searchtype=author&query=Lee%2C+J+S">Jun Sik Lee</a>, <a href="/search/cond-mat?searchtype=author&query=Morley%2C+S">Sophie Morley</a>, <a href="/search/cond-mat?searchtype=author&query=Roy%2C+S">Sujoy Roy</a>, <a href="/search/cond-mat?searchtype=author&query=Fabbris%2C+G">Gilberto Fabbris</a>, <a href="/search/cond-mat?searchtype=author&query=Blackburn%2C+E">Elizabeth Blackburn</a>, <a href="/search/cond-mat?searchtype=author&query=Feiguin%2C+A">Adrian Feiguin</a>, <a href="/search/cond-mat?searchtype=author&query=Bansil%2C+A">Arun Bansil</a>, <a href="/search/cond-mat?searchtype=author&query=Lee%2C+W">Wei-Sheng Lee</a>, <a href="/search/cond-mat?searchtype=author&query=Lindenberg%2C+A">Aaron Lindenberg</a>, <a href="/search/cond-mat?searchtype=author&query=Chowdhury%2C+S">Sugata Chowdhury</a>, <a href="/search/cond-mat?searchtype=author&query=Dunne%2C+M">Mike Dunne</a>, <a href="/search/cond-mat?searchtype=author&query=Turner%2C+J+J">Joshua J.

These materials are at the center of a host of novel types of experiments, however, there are notably few pathways to directly probe their magnetic structure. We report the magnetic order within a single crystal of NiPS$_3$ and show it can be accessed with resonant elastic X-ray diffraction along the edge of the vdW planes in a carefully grown crystal by detecting structurally forbidden resonant magnetic X-ray scattering. We find the magnetic order parameter has a critical exponent of $尾\sim0.36$, indicating that the magnetism of these vdW crystals is more adequately characterized by the three-dimensional (3D) Heisenberg universality class. We verify these findings with first-principle density functional theory, Monte-Carlo simulations, and density matrix renormalization group calculations. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.07948v4-abstract-full').style.display = 'none'; document.getElementById('2310.07948v4-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 18 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 11 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.07787">arXiv:2305.07787</a> <span> [<a href="https://arxiv.org/pdf/2305.07787">pdf</a>, <a href="https://arxiv.org/format/2305.07787">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Other Condensed Matter">cond-mat.other</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Quantum Physics">quant-ph</span> </div> </div> <p class="title is-5 mathjax"> On Ultrafast X-ray Methods for Magnetism </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Plumley%2C+R">Rajan Plumley</a>, <a href="/search/cond-mat?searchtype=author&query=Chitturi%2C+S">Sathya Chitturi</a>, <a href="/search/cond-mat?searchtype=author&query=Peng%2C+C">Cheng Peng</a>, <a href="/search/cond-mat?searchtype=author&query=Assefa%2C+T">Tadesse Assefa</a>, <a href="/search/cond-mat?searchtype=author&query=Burdet%2C+N">Nicholas Burdet</a>, <a href="/search/cond-mat?searchtype=author&query=Shen%2C+L">Lingjia Shen</a>, <a href="/search/cond-mat?searchtype=author&query=Reid%2C+A">Alex Reid</a>, <a href="/search/cond-mat?searchtype=author&query=Dakovski%2C+G">Georgi Dakovski</a>, <a href="/search/cond-mat?searchtype=author&query=Seaberg%2C+M">Matthew Seaberg</a>, <a href="/search/cond-mat?searchtype=author&query=O%27Dowd%2C+F">Frank O'Dowd</a>, <a href="/search/cond-mat?searchtype=author&query=Montoya%2C+S">Sergio Montoya</a>, <a href="/search/cond-mat?searchtype=author&query=Chen%2C+H">Hongwei Chen</a>, <a href="/search/cond-mat?searchtype=author&query=Okullo%2C+A">Alana Okullo</a>, <a href="/search/cond-mat?searchtype=author&query=Mardanya%2C+S">Sougata Mardanya</a>, <a href="/search/cond-mat?searchtype=author&query=Kevan%2C+S">Stephen Kevan</a>, <a href="/search/cond-mat?searchtype=author&query=Fischer%2C+P">Peter Fischer</a>, <a href="/search/cond-mat?searchtype=author&query=Fullerton%2C+E">Eric Fullerton</a>, <a href="/search/cond-mat?searchtype=author&query=Sinha%2C+S">Sunil Sinha</a>, <a href="/search/cond-mat?searchtype=author&query=Colocho%2C+W">William Colocho</a>, <a href="/search/cond-mat?searchtype=author&query=Lutman%2C+A">Alberto Lutman</a>, <a href="/search/cond-mat?searchtype=author&query=Decker%2C+F">Franz-Joseph Decker</a>, <a href="/search/cond-mat?searchtype=author&query=Roy%2C+S">Sujoy Roy</a>, <a href="/search/cond-mat?searchtype=author&query=Fujioka%2C+J">Jun Fujioka</a>, <a href="/search/cond-mat?searchtype=author&query=Tokura%2C+Y">Yoshinori Tokura</a>, <a href="/search/cond-mat?searchtype=author&query=Minitti%2C+M+P">Michael P.

As it relates to magnetism and "magnetic-type" systems, advanced methods are being developed for studying ultrafast magnetic responses on the time-scales at which they occur. We describe three capabilities which have the potential to seed new directions in this area and present original results from each: pump-probe x-ray scattering with low energy excitation, x-ray photon fluctuation spectroscopy, and ultrafast diffuse x-ray scattering. By combining these experimental techniques with advanced modeling together with machine learning, we describe how the combination of these domains allows for a new understanding in the field of magnetism. Finally, we give an outlook for future areas of investigation and the newly developed instruments which will take us there. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.07787v1-abstract-full').style.display = 'none'; document.getElementById('2305.07787v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2304.12485">arXiv:2304.12485</a> <span> [<a href="https://arxiv.org/pdf/2304.12485">pdf</a>, <a href="https://arxiv.org/format/2304.12485">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Superconductivity">cond-mat.supr-con</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Strongly Correlated Electrons">cond-mat.str-el</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevB.108.L201111">10.1103/PhysRevB.108.L201111 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Interplay between atomic fluctuations and charge density waves in La$_{2-x}$Sr$_{x}$CuO$_{4}$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Shen%2C+L">L.

We have combined a set of x-ray scattering techniques to study La$_{1.88}$Sr$_{0.12}$CuO$_{4}$ ($T_\mathrm{CDW}$~$\approx$~80\,K) to shed light on this discussion. We observe the emergence of a crystal structure, which is consistent with the CDW modulation in symmetry, well above $T_\mathrm{CDW}$. This global structural change also induces strong fluctuations of local atomic disorder in the intermediate temperature region. At $T_\mathrm{CDW}$, the temperature dependence of this structure develops a kink, while the atomic disorder is minimized. We find that the atomic relaxation dynamics cross over from a cooperative to an incoherent response at $T_\mathrm{CDW}$. These results reveal a rich interplay between the CDWs and atomic fluctuations of distinct spatio-temporal scales. For example, the CDW coherence is enhanced on quasi-elastic timescales by incoherent atomic relaxation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2304.12485v1-abstract-full').style.display = 'none'; document.getElementById('2304.12485v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 24 April, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2209.11528">arXiv:2209.11528</a> <span> [<a href="https://arxiv.org/pdf/2209.11528">pdf</a>, <a href="https://arxiv.org/format/2209.11528">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Strongly Correlated Electrons">cond-mat.str-el</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Superconductivity">cond-mat.supr-con</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1073/pnas.2400727121">10.1073/pnas.2400727121 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Orbital-selective time-domain signature of nematicity dynamics in the charge-density-wave phase of La$_{1.65}$Eu$_{0.2}$Sr$_{0.15}$CuO$_4$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Bluschke%2C+M">Martin Bluschke</a>, <a href="/search/cond-mat?searchtype=author&query=Gupta%2C+N+K">Naman K.

Using pump-probe time-resolved resonant x-ray scattering on the (0 0 1) Bragg peak at the Cu $L_3$ and O $K$ resonances, we investigate non-equilibrium dynamics of $Q_a = Q_b = 0$ nematic order and its association with both charge density wave (CDW) order and lattice dynamics in La$_{1.65}$Eu$_{0.2}$Sr$_{0.15}$CuO$_4$. The orbital selectivity of the resonant x-ray scattering cross-section allows nematicity dynamics associated with the planar O 2$p$ and Cu 3$d$ states to be distinguished from the response of anisotropic lattice distortions. A direct time-domain comparison of CDW translational-symmetry breaking and nematic rotational-symmetry breaking reveals that these broken symmetries remain closely linked in the photoexcited state, consistent with the stability of CDW topological defects in the investigated pump fluence regime. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2209.11528v3-abstract-full').style.display = 'none'; document.getElementById('2209.11528v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 23 September, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">19 pages, 5 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1608.03098">arXiv:1608.03098</a> <span> [<a href="https://arxiv.org/pdf/1608.03098">pdf</a>, <a href="https://arxiv.org/ps/1608.03098">ps</a>, <a href="https://arxiv.org/format/1608.03098">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Mesoscale and Nanoscale Physics">cond-mat.mes-hall</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevB.96.014109">10.1103/PhysRevB.96.014109 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Bragg projection ptychography on niobium phase domain </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Burdet%2C+N">Nicolas Burdet</a>, <a href="/search/cond-mat?searchtype=author&query=Shi%2C+X">Xiaowen Shi</a>, <a href="/search/cond-mat?searchtype=author&query=Clark%2C+J+N">Jesse N.
