Interests</h2> <p class="wp-block-opus-core-block-rewrite-op text-none">Professor Roland studies the properties of strongly interacting matter under extreme conditions, such as those achieved in collisions of ultra-relativistic lead-lead collisions at CERN’s Large Hadron Collider. At the temperatures and densities reached in these collisions, matter exists in the form of a Quark-Gluon Plasma (QGP), a decon ned state of quarks and gluons in thermal equilibrium. Results from LHC and earlier experiments have revealed the QGP to have unique properties compared to any other known state of matter, such as a very small shear viscosity to entropy density ratio. The MIT Relativistic Heavy Ion Group works on the CMS experiment at CERN, using jet, photon and heavy-avor probes, as well as momentum correlations, to extract the thermodynamic and transport properties of the QGP from collision data. Recent work by Roland’s group has dramatically improved the precision of this process and revealed QGP-like signatures also in smaller collision systems such as proton-proton and proton-lead. Studies of parton propagation through the QGP have provided first information on the angular and momentum pattern of QCD energy radiation. Future high-luminosity data from the LHC will allow a continuation of QGP studies with unprecedented statistical precision and highly differential signatures, such as Z+jet correlations. The MIT group is preparing a new calorimeter trigger system and fast online event selection tools to maximize these opportunities.</p> <h2 class="wp-block-opus-core-block-rewrite-oh text-none">Biographical Sketch</h2> <p class="wp-block-opus-core-block-rewrite-op text-none">Professor Roland joined the Heavy Ion Group in the MIT Department of Physics in September 2000 from CERN, where he was a Scientific Associate. In July 2004, he was promoted to Associate Professor of Physics at MIT. He received his Ph.D. from the Institut fur Kernphysik, Frankfurt, in 1993. He was promoted to Full Professor in July 2011.</p> <figure class="wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper"> <iframe title="An Invitation to New Students" width="500" height="281" src="https://www.youtube.com/embed/YcuKaphreT0?feature=oembed" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe> </div><figcaption class="wp-element-caption">Junior Lab – An Invitation to New Students<br>Courtesy of MIT OpenCourseWare | YouTube</figcaption></figure> </div> </div> </div> </div> </div> <div class="faculty__featured-news"> <div class="container"> <div class="row"> <div class="col-12 col-md-6 offset-lg-1"> <div class="faculty__featured-news-image"> <div class="d-lg-none faculty__featured-news-body-label tag-heading"> In the news </div> <picture> <source srcset="https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-578x410-c-default.jpg 1x, https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-1156x820-c-default.jpg 2x" media="all and (min-width: 1080px)" type="image/jpeg"> <source srcset="https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-578x410-c-default.jpg 1x, https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-1156x820-c-default.jpg 2x" media="all and (min-width: 768px) and (max-width: 1079px)" type="image/jpeg"> <source srcset="https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-578x410-c-default.jpg 1x, https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-1156x820-c-default.jpg 2x" type="image/jpeg"> <img src="https://physics.mit.edu/wp-content/uploads/2023/05/20230501_sphenix-assembly-hr-578x410-c-default.jpg" alt="triptych of assembly of sPHENIX Detector over time" typeof="foaf:Image"> </picture> </div> </div> <div class="col-12 col-md-6 col-lg-4"> <div class="faculty__featured-news-body"> <div class="d-none d-lg-block faculty__featured-news-body-label tag-heading"> In the news </div> <h2 class="faculty__featured-news-title"> <a href="https://physics.mit.edu/news/sphenix-detector-is-ready-for-collisions/">sPHENIX Detector is Ready for Collisions</a> </h2> <p>More than a decade in the making, the advanced particle detector moves from assembly to active experiment</p> </div> </div> </div> </div> </div> <div class="faculty__awards-and-honors"> <div class="container"> <div class="row"> <div class="col"> <h2 class="faculty__awards-and-honors-title tag-heading">Awards & Honors</h2> </div> </div> <div class="row"> <div class="col col-lg-8 offset-lg-1"> <ul class="list-unstyled"> <li class="faculty__award"> <strong>2013</strong> <span>//</span> American Physical Society Fellow "<em"For his pioneering work on particle correlations in high-energy nuclear interactions, which led to the discovery of triangular flow, and his role in steering the PHOBOS and CMS heavy-ion physics programs.</em>" </li> </ul> </div> </div> </div> </div> <div class="faculty__publications"> <div class="container"> <div class="row"> <div class="col"> <h2 class="faculty__publications-title tag-heading">Key Publications</h2> </div> </div> <div class="row"> <div class="col col-lg-8 offset-lg-1"> <ul class="list-unstyled"> <li class="faculty__publication"> <p>“Ratios of charged antiparticles to particles near mid-rapidity in Au+Au collisions at sqrt(s) = 130 GeV”, B.
