Topology of a parity–time symmetric non-Hermitian rhombic lattice

S Zhang, L **, Z Song - Chinese Physics B, 2022 - iopscience.iop.org
We investigate the topological properties of a trimerized parity–time (𝒫𝒯) symmetric non-
Hermitian rhombic lattice. Although the system is 𝒫𝒯-symmetric, the topology is not inherited …

Static synthetic gauge field control of double optomechanically induced transparency in a closed-contour interaction scheme

B Sütlüoğlu, C Bulutay - Physical Review A, 2021 - APS
We study theoretically an optical cavity and a parity-time (PT)-symmetric pair of mechanical
resonators, where all oscillators are pairwise coupled, forming an optomechanical system …

Symmetry and Topology of the Topological Counterparts in Non‐Hermitian Systems

JQ Li, JJ Li, L Qi, ZX Zhang, J Cao, WX Cui… - Annalen der …, 2023 - Wiley Online Library
The symmetries and topological properties of the topological counterparts in 1D non‐
Hermitian systems are investigated. It is found that, after applying the non‐unitary similarity …

Quantum synchronization in an asymmetric coupled optomechanical system

JT Sun, XX Yi, HD Liu - Physica Scripta, 2025 - iopscience.iop.org
In this work, we investigate the quantum synchronization and ϕ synchronization of two
mechanical oscillators of different frequencies in two optomechanical systems with …

Quantum nonlinear effect in a dissipatively coupled optomechanical system

WQ Yang, W Niu, YH Ma, WZ Zhang - Optics Express, 2024 - opg.optica.org
A full-quantum approach is used to study the quantum nonlinear properties of a compound
Michelson-Sagnac interferometer optomechanical system. By deriving the effective …

Non-Hermicity-induced multistability in two-level atom-cavity optomechanics

Y Chengyong, KA Yasir, G **anlong - The European Physical Journal Plus, 2023 - Springer
Non-Hermitian physics of optical as well as atomic systems is crucial for modern quantum
mechanics and is the subject of increasing investigations. Here, we investigate the multi …
