Speaker's Brief Introduction：Tarik Yefsah is a CNRS permanent researcher at the école Normale Supérieure in France, where he leads an experimental group studying ultracold quantum gases. After earning his PhD at the école Normale Supérieure and Paris VI University, he became a postdoctoral fellow at MIT. He then joined the Max Planck Institute for Quantum Optics in Germany for a short-term stay as a postdoctoral fellow and visiting scientist. His research focuses on ultracold atoms, quantum many-body systems, and quantum simulation.
Abstract: The last decades have seen the emergence of ultracold atom experiments as powerful platforms for the exploration of complex many-body systems, owing to their ability to probe large ensembles of particles in a well-characterized, tunable, and isolated environment.
Among the various quantum many-body problems within reach of quantum gas experiments, interacting fermionic systems play a special role. While they constitute a cornerstone of quantum matter covering a broad fundamental and technological scope, their understanding still represents a major challenge for existing theoretical approaches, which are widely plagued by the infamous sign-problem.
In this talk, I will present our recent work on quantum gas microscopy of fermionic many-body systems in continuous space, how we characterize them at previously inaccessible levels of resolution, and gain new insight into their microscopic inner workings.
