Non-Gaussian Phase Transition and Cascade of Instabilities in the Dissipative Quantum Rabi Model
Mingyu Kang, Yikang Zhang, Kenneth R. Brown +1
The open quantum Rabi model describes a two-level system coupled to a harmonic oscillator. A Gaussian phase transition for the nonequilibrium steady states has been predicted when…

Quantum Simulation of Spin-Boson Models with Structured Bath
Ke Sun, Mingyu Kang, Hanggai Nuomin +4
The spin-boson model, involving spins interacting with a bath of quantum harmonic oscillators, is a widely used representation of open quantum systems. Trapped ions present a natur…
