Lasing and counter-lasing phase transitions in a cavity QED system
Kevin C. Stitely, Andrus Giraldo, Bernd Krauskopf +1
We study the effect of spontaneous emission and incoherent atomic pumping on the nonlinear semiclassical dynamics of the unbalanced Dicke model -- a generalization of the Dicke mod…
Chaotic switching in driven-dissipative Bose-Hubbard dimers: when a flip bifurcation meets a T-point in
Andrus Giraldo, Neil G. R. Broderick, Bernd Krauskopf
The Bose--Hubbard dimer model is a celebrated fundamental quantum mechanical model that accounts for the dynamics of bosons at two interacting sites. It has been realized experimen…
Infinitely Many Multipulse Solitons of Different Symmetry Types in the Nonlinear Schrödinger Equation with Quartic Dispersion
Ravindra Bandara, Andrus Giraldo, Neil G. R. Broderick +1
We show that the generalised nonlinear Schrödinger equation (GNLSE) with quartic dispersion supports infinitely many multipulse solitons for a wide parameter range of the dispersio…
Superradiant Switching, Quantum Hysteresis, and Oscillations in a Generalized Dicke Model
Kevin Stitely, Stuart J Masson, Andrus Giraldo +2
We demonstrate quantum signatures of deterministic nonlinear dynamics in the transition to superradiance of a generalized open Dicke model with different coupling strengths for the…
The nonlinear semiclassical dynamics of the unbalanced, open Dicke model
Kevin Stitely, Andrus Giraldo, Bernd Krauskopf +1
In recent years there have been significant advances in the study of many-body interactions between atoms and light confined to optical cavities. One model which has received wides…
The driven-dissipative Bose-Hubbard dimer: phase diagram and chaos
A. Giraldo, B. Krauskopf, N. G. R. Broderick +2
We present the phase diagram of the mean-field driven-dissipative Bose-Hubbard dimer model. For a dimer with repulsive on-site interactions () and coherent driving we prove th…
