A Platform for Cavity Quantum Electrodynamics with Rydberg Atom Arrays
Abstract: In cavity quantum electrodynamics (cavity QED) systems, the realization of strong coupling between light and atoms plays a critical role in studying quantum optics and entanglement. At the same time, the Rydberg atom arrays provide a promising platform for exploring many-body physics. However, with the Rydberg-mediated interactions, the atoms mainly interact with each other locally. Combining the cavity QED and Rydberg arrays systems opens up new research directions in many-body physics with long-range interactions, creating a fully connected quantum network.
Polarons and Topological Effects in Ultracold Atomic Gases
Abstract: Ultracold atomic gases have proven to provide valuable platforms to simulate quantum systems arising in disparate areas of physics. Polarons are well-studied quasiparticles in solid-state systems that describe an electron dressed by lattice distortions. The so-called Frohlich model is the typical starting point for theoretically describing such systems. More recently, polarons arising in Bose-Einstein condensates have been the focus of much attention, both theoretical and experimental.
