Institutskolloquium: Prof. Dr. Ana Asenjo-Garcia (Columbia University, NY, USA) spricht zum Thema:
Quantum many-body physics with atoms and photons
Abstract
Ordered arrays of atoms exhibit remarkable collective optical properties, as dissipation in the form of photon emission is correlated. In this talk, I will discuss the many-body out-of-equilibrium physics of arrays of atoms in free space and in one-dimensional baths. I will focus on the problem of Dicke superradiance, where a collection of excited emitters synchronizes as they decay, emitting a short and intense pulse of light. Superradiance remains an open problem in extended systems due to the exponential growth of complexity with atom number. I will show that superradiance is a universal phenomenon in ordered arrays. Our predictions can be tested in state of the art experiments with arrays of neutral atoms, molecules, and solid-state emitters and pave the way towards understanding the role of many-body decay in quantum simulation, metrology, and lasing.
Das Kolloquium wird "hybrid" durchgeführt, kann also sowohl im Hörsaal als auch über zoom verfolgt werden. Die Anmeldedaten werden im Vorfeld über die üblichen Mailverteiler versandt oder können unter gd-at-physik.hu-berlin.de erfragt werden.
