[HTML][HTML] Electrically coupled optomechanical cavities as a tool for quantum nondemolition measurement

J Wójcik, G Chimczak - Physics Letters A, 2023 - Elsevier
We present a new model of two electrically coupled optomechanical cavities. This model is
based on the recently presented proposal [Physical Review A 103 (2021) 043509]. We …

Rotation-time symmetry in bosonic systems and the existence of exceptional points in the absence of symmetry

E Lange, G Chimczak, A Kowalewska-Kudłaszyk… - Scientific Reports, 2020 - nature.com
We study symmetries of open bosonic systems in the presence of laser pumping. Non-
Hermitian Hamiltonians describing these systems can be parity-time (PT) symmetric in …

Non-local correlation between two coupled qubits interacting nonlinearly with a two-mode cavity: Bell function, Trace norm and Bures distance quantifiers

ABA Mohamed, EM Khalil, S Abdel-Khalek - Physica Scripta, 2020 - iopscience.iop.org
In this paper, we study the dynamics of two coupled qubits interacting with a two-mode
parametric amplifier cavity through the nonlinear interactions of the photon processes under …

Quantum transient heat transport in the hyperparametric oscillator

JY Han, D Leykam, DG Angelakis, J Thingna - Physical Review A, 2021 - APS
We explore nonequilibrium quantum heat transport in nonlinear bosonic systems in the
presence of a non-Kerr-type interaction governed by hyperparametric oscillation due to two …
