Dissipative phase transitions: Independent versus collective decay and spin squeezing
Tony E. Lee, Ching-Kit Chan, Susanne F. Yelin
We study the XY model with infinite-range interactions (Lipkin-Meshkov-Glick model) in the presence of dissipation from spontaneous decay. We show that independent and collective d…
Quantum interference between independent reservoirs in open quantum systems
Ching-Kit Chan, Guin-Dar Lin, Susanne F. Yelin +1
When a quantum system interacts with multiple reservoirs, the environmental effects are usually treated in an additive manner. We show that this assumption breaks down for non-Mark…
Heralded magnetism in non-Hermitian atomic systems
Tony E. Lee, Ching-Kit Chan
Quantum phase transitions are usually studied in terms of Hermitian Hamiltonians. However, cold-atom experiments are intrinsically non-Hermitian due to spontaneous decay. Here, we…
Entanglement tongue and quantum synchronization of disordered oscillators
Tony E. Lee, Ching-Kit Chan, Shenshen Wang
We study the synchronization of dissipatively-coupled van der Pol oscillators in the quantum limit, when each oscillator is near its quantum ground state. Two quantum oscillators w…
