- 요약In my thesis work, I have explored novel ways to experimentally simulate nonequilibrium quantum models in a cavity quantum electrodynamics (cavity QED) platform consisting of many atoms collectively coupled to an optical cavity. Quantum simulation is a burgeoning field, both in atomic physics and beyond, with the potential to answer many open questions about complex quantum systems. In particular, many of these systems are expected to exhibit nontrivial dynamical phases of matter not observable in thermodynamic equilibrium, which are challenging to observe in nature but could be realized with a controllable quantum simulator. To this end, cavity QED offers the ability to natively engineer infinite-range nonlocal interactions, a feature present in many quantum magnetism and quantum optics models. This makes the platform well-suited to study these models and explore their behavior out of equilibrium.A key breakthrough in my thesis work was developing a simulator to study dynamics in the BCS model of superconductivity using an ensemble of thermal spins interacting through the cavity. Although this model has been predicted to exhibit three distinct phases of dynamics after quenching the system out of equilibrium, an observation of these phases in real superconducting or superfluid platforms has remained out of reach. Thanks to the ability to engineer cavity-mediated atom-atom interactions and control single-particle energy shifts in our system, I successfully utilized an Anderson pseudospin mapping to experimentally observe all three predicted dynamical phases for the first time in any platform. By expanding the scope of this mapping in straightforward ways, I was able to explore even richer dynamics and performed a study identifying and contrasting two distinct many body energy gaps in the system. My work opens the door towards engineering even richer and more complex quantum models, such as superconductors with nontrivial topology and synthetic lattices experiencing coherent correlation spreading across their sites.
