The workshop brought together experts from around the world to discuss the exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter and gravitational waves. The primary objective of the workshop was to lay the groundwork for an international TVLBAI proto-collaboration. This collaboration aims to unite researchers from different institutions to strategize and secure funding for terrestrial large-scale AI projects. The ultimate goal is to create a roadmap detailing the design and technology choices for one or more km-scale detectors, which will be operational in the mid-2030s. The key sections of this report present the physics case and technical challenges, together with a comprehensive overview of the discussions at the workshop together with the main conclusions. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2310.08183v1-abstract-full').style.display = 'none'; document.getElementById('2310.08183v1-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 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2023. </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">Summary of the Terrestrial Very-Long-Baseline Atom Interferometry Workshop held at CERN: https://indico.cern.ch/event/1208783/</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2201.07789">arXiv:2201.07789</a> <span> [<a href="https://arxiv.org/pdf/2201.07789">pdf</a>, <a href="https://arxiv.org/format/2201.07789">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Methods for Astrophysics">astro-ph.IM</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="General Relativity and Quantum Cosmology">gr-qc</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Atomic Physics">physics.atom-ph</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/10.1140/epjqt/s40507-022-00147-w">10.1140/epjqt/s40507-022-00147-w <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/gr-qc?searchtype=author&query=Alonso%2C+I">Ivan Alonso</a>, <a href="/search/gr-qc?searchtype=author&query=Alpigiani%2C+C">Cristiano Alpigiani</a>, <a href="/search/gr-qc?searchtype=author&query=Altschul%2C+B">Brett Altschul</a>, <a href="/search/gr-qc?searchtype=author&query=Araujo%2C+H">Henrique Araujo</a>, <a href="/search/gr-qc?searchtype=author&query=Arduini%2C+G">Gianluigi Arduini</a>, <a href="/search/gr-qc?searchtype=author&query=Arlt%2C+J">Jan Arlt</a>, <a href="/search/gr-qc?searchtype=author&query=Badurina%2C+L">Leonardo Badurina</a>, <a href="/search/gr-qc?searchtype=author&query=Balaz%2C+A">Antun Balaz</a>, <a href="/search/gr-qc?searchtype=author&query=Bandarupally%2C+S">Satvika Bandarupally</a>, <a href="/search/gr-qc?searchtype=author&query=Barone%2C+B+C+B+M">Barry C Barish Michele Barone</a>, <a href="/search/gr-qc?searchtype=author&query=Barsanti%2C+M">Michele Barsanti</a>, <a href="/search/gr-qc?searchtype=author&query=Bass%2C+S">Steven Bass</a>, <a href="/search/gr-qc?searchtype=author&query=Bassi%2C+A">Angelo Bassi</a>, <a href="/search/gr-qc?searchtype=author&query=Battelier%2C+B">Baptiste Battelier</a>, <a href="/search/gr-qc?searchtype=author&query=Baynham%2C+C+F+A">Charles F.

The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. Prospective applications include metrology, geodesy and measurement of terrestrial mass change due to, e.g., climate change, and fundamental science experiments such as tests of the equivalence principle, searches for dark matter, measurements of gravitational waves and tests of quantum mechanics. We review the current status of cold atom technologies and outline the requirements for their space qualification, including the development paths and the corresponding technical milestones, and identifying possible pathfinder missions to pave the way for missions to exploit the full potential of cold atoms in space. Finally, we present a first draft of a possible road-map for achieving these goals, that we propose for discussion by the interested cold atom, Earth Observation, fundamental physics and other prospective scientific user communities, together with ESA and national space and research funding agencies. <a class="is-size-7" style="white-space: nowrap;"
