PT-symmetry breaking phase transitions in an LMG dimer
Simon Kothe, Christopher Oliver, Peter Kirton
The open Lipkin-Meshkov-Glick (LMG) model provides a prototype of a dissipative phase transition which can be analyzed using mean-field theory. By combining the physics of this mod…

Collective Enhancement of Photon Blockade via Two-Photon Interactions
Lijuan Dong, Aanal Jayesh Shah, Peter Kirton +2
Analogous to Coulomb blockade for electrons, photon blockade is a key quantum optical effect in which the presence of one photon prevents the transmission of subsequent ones throug…

Dissipative Phase Transition in the Two-Photon Dicke Model
Aanal Jayesh Shah, Peter Kirton, Simone Felicetti +1
We explore the dissipative phase transition of the two-photon Dicke model, a topic that has garnered significant attention recently. Our analysis reveals that while single-photon l…
