SUMMARY:Workshop / Seminar:Quantum Research Institute | Thinking Inside the Box: Quantum Many-Body Frontiers with Ultracold Fermions
DESCRIPTION:Zoom: In the Meeting Invite\nIn-Person: West Hall 411\n\nAbstract:\nRecent progress in the control of complex quantum systems has made it possible to revisit\nlong-standing questions\, realize thought experiments once deemed inaccessible\, and explore\nnew terrain. Our contribution to this progress has been the development of an experimental\nplatform that creates ultracold quantum fluids in spatiotemporally programmable optical\npotentials\, engineered with advanced electro-optic devices.\nIn this talk\, I will share our explorations into the physics of fermions confined in ‘boxes of\nlight’\, a deceptively simple stage that gives rise to remarkably rich behavior [1]. Highlights\ninclude few-body recombination in multicomponent fermions [2\,3]\, the first observation of\nthe quantum Joule–Thomson effect for fermions [4]\, strong-drive spectroscopy of Fermi-\npolaron quasiparticles [5]\, the first direct observation of the Lindhard response [6]\, the\nobservation of the emergence and breakdown of Fermi’s Golden Rule in a strongly\ninteracting system [7]\, and the unveiling of a new correspondence between short-time and\nlong-time behavior in quantum dynamics [8]. Together\, these studies span a wide range of\ntopics—thermodynamics\, few-body physics\, quantum impurity problems\, and\nhydrodynamics—showcasing both long-predicted effects finally brought into view and\nsurprising new phenomena.\n[1] N.

Li et al.\, arXiv:2605.06666 (2026)\n\nBio\nNir Navon is an Associate Professor of Physics at Yale University. He received his Ph.D. in 2011 from the École Normale Supérieure in Paris (France)\, where he worked with Christophe Salomon and Frédéric Chevy on the thermodynamics of ultracold Bose and Fermi gases. Afterwards\, he worked on trapped-ion quantum information in the group of Roee Ozeri at the Weizmann Institute of Science (Israel). From 2013 to 2018\, he was a Junior Research Fellow at Trinity College\, Cambridge (UK)\, working with Zoran Hadzibabic on homogeneous Bose gases in optical box traps. He joined the Yale faculty in 2017.\n\nHis group has built an apparatus that produces strongly interacting Fermi gases in programmable potentials. This apparatus has made it possible to experimentally address quantum many-body problems where theory offers few\, if any\, reliable answers. The group's recent work includes the observation of the as-yet unexplained recombination dynamics of three-component fermions\, the emergence of sound in a Fermi fluid with tunable interactions\, the strongly driven Fermi polaron\, the first observation of the quantum Joule-Thomson effect for fermions\, and the emergence and breakdown of Fermi's Golden Rule in a many-body system. His awards and honors include a Packard Fellowship (2017)\, a Sloan Research Fellowship (2019)\, an NSF CAREER Award (2020)\, the New Horizons Lectureship in Physics at the Solvay Institutes (2023)\, Outstanding Referee of the APS (2023)\, and a Scialog Fellowship of the RCSA (2025).
