QSimFP QBH Seminar: Quantum field simulator for dynamics in curved spacetime

"In this seminar I will introduce the capabilities of ultracold gases to address fundamental questions in quantum field theory. I will introduce the experimental capabilities in preparation and detection of quantum fields in atomic gases. A special focus will be on our latest result on the implementation of curved spacetime for a scalar massless quantum field. We have shown that positive as well as negative curvature can be experimentally realized and can be dialed in as needed. We also used the experiment/simulator to reveal particle production in an accelerating, decelerating and constantly expanding spacetime. Employing Sakharov oscillations for detecting the production of excitations opens a window to add to the power spectrum also phase information about the excitations."
