Competing Soft Modes and Tunable Multicriticality in a Generalized Two-Mode Quantum Rabi Model
Xiufeng Cao, Ofri Adiv, Neil G. R. Broderick
Multicritical phenomena play a central role in quantum many-body systems, yet their microscopic origin in light--matter platforms remains largely unexplored. Here we investigate a…

Nonlinear Dynamics of a Dicke Model for V-Type Atoms
Ofri Adiv, Bernd Krauskopf, Scott Parkins
We study the nonlinear, semiclassical dynamics of an open spin-1 (three-level) variant of the traditional Dicke model. In particular, we focus on V-type energy-level configurations…

Dynamics of a Generalized Dicke Model for Spin-1 Atoms
Ofri Adiv, Scott Parkins
The Dicke model is a staple of theoretical cavity Quantum Electrodynamics (cavity QED), describing the interaction between an ensemble of atoms and a single radiation mode of an op…
