Detecting axion dark matter with Rydberg atoms via induced electric dipole transitions
Georg Engelhardt, Amit Bhoonah, W. Vincent Liu
Long-standing efforts to detect axions are driven by two compelling prospects, naturally accounting for the absence of charge-conjugation and parity symmetry breaking in quantum ch…
Unified Light-Matter Floquet Theory and its Application to Quantum Communication
Georg Engelhardt, Sayan Choudhury, W. Vincent Liu
Periodically-driven quantum systems can exhibit a plethora of intriguing non-equilibrium phenomena that can be analyzed using Floquet theory. Naturally, Floquet theory is employed…
Discrete time crystals enforced by Floquet-Bloch scars
Biao Huang, Tsz-Him Leung, Dan Stamper-Kurn +1
We analytically identify a new class of quantum scars protected by spatiotemporal translation symmetries, dubbed Floquet-Bloch scars. They distinguish from previous (quasi-)static…
Manipulating Goldstone modes via the superradiant light in a bosonic lattice gas inside a cavity
Huan Wang, Shuai Li, Maksims Arzamasovs +2
We study the low-energy excitations of a bosonic lattice gas with cavity-mediated interactions. By performing two successive Hubbard-Stratonovich transformations, we derive an effe…
Breached pair superfluidity: a brief review
W. Vincent Liu
Interior gap superfluidity was introduced together with Frank Wilczek. Later on together with our collaborators, we generalized this new possibility of superfluidity to a broader c…
Dynamical signatures of point-gap Weyl semimetal
Haiping Hu, Erhai Zhao, W. Vincent Liu
We demonstrate a few unique dynamical properties of point-gap Weyl semimetal, an intrinsic non-Hermitian topological phase in three dimensions. We consider a concrete model where a…
