Polaron-transformed dissipative Lipkin-Meshkov-Glick Model
Wassilij Kopylov, Gernot Schaller
We investigate the Lipkin-Meshkov-Glick model coupled to a thermal bath. Since the isolated model itself exhibits a quantum phase transition, we explore the critical signatures of…
Cooperative efficiency boost for quantum heat engines
David Gelbwaser-Klimovsky, Wassilij Kopylov, Gernot Schaller
The power and efficiency of many-body heat engines can be boosted by performing cooperative non-adiabatic operations in contrast to the commonly used adiabatic implementations. Her…
Wiseman-Milburn Control for the Lipkin-Meshkov-Glick Model
Sven Zimmermann, Wassilij Kopylov, Gernot Schaller
We apply a measurement-based closed-loop control scheme to the dissipative Lipkin-Meshkov-Glick model. Specifically, we use the Wiseman-Milburn feedback master equation to control…
Interplay of coherent and dissipative dynamics in condensates of light
Milan Radonjic, Wassilij Kopylov, Antun Balaz +1
Based on the Lindblad master equation approach we obtain a detailed microscopic model of photons in a dye-filled cavity, which features condensation of light. To this end we genera…
Nonadiabatic dynamics of the excited states for the Lipkin-Meshkov-Glick model
Wassilij Kopylov, Gernot Schaller, Tobias Brandes
We theoretically investigate the impact of the excited state quantum phase transition on the adiabatic dynamics for the Lipkin-Meshkov-Glick model. Using a time dependent protocol,…
Dissipative Two-Mode Tavis-Cummings Model with Time-Delayed Feedback Control
Wassilij Kopylov, Milan Radonjić, Tobias Brandes +2
We investigate the dynamics of a two-mode laser system by extending the two-mode Tavis-Cummings model with dissipative channels and incoherent pumping and by applying the mean-fiel…
