Squeezed superradiant lasing of a quantum many-body emitter
Da-Wu Xiao, Chong Chen, Ren-Bao Liu
In conventional lasers, the emitters are typically incoherent, radiating photons independently; in superradiant lasers, many coherent emitters radiate photons collectively, but the…
Polynomial complexity of open quantum system problems
Chong Chen, Ren-Bao Liu
Open quantum systems (OQS's) are ubiquitous in non-equilibrium quantum dynamics and in quantum science and technology. Solving the dynamics of an OQS in a quantum many-body bath ha…
Structures in higher-order quantum correlations due to non-spatial symmetries
Li Sun, Chong Chen, Ren-Bao Liu
Quantum nonlinear spectroscopy (QNS) via a quantum sensor can access types of -th order contour-time-ordered correlations (CTOCs) arising from different orderings of q…
Lee-Yang Zeros of a Bosonic system associated with a single trapped ion
Wenjie Shao, Yulian Chen, Ren-bao Liu +1
Zeros of partition functions, in particular Lee-Yang zeros, in a complex plane provide important information for understanding phase transitions. A recent discovery on the equivale…
