Entanglement signatures of quantum criticality in Floquet non-Hermitian topological systems
Siyuan Cheng, Rui Xie, Xiaosen Yang +2
The entanglement entropy can be an effective diagnostic tool for probing topological phase transitions. In one-dimensional single particle systems, the periodic driving generates a…
Impact of Nonreciprocal Hopping on Localization in Non-Hermitian Quasiperiodic Systems
Xianqi Tong, Yiling Zhang, Bin Li +1
We study the non-Hermitian Aubry-André-Harper model, incorporating complex phase modulation, unmodulated and modulated nonreciprocal hopping. Using Avila's global theory, we derive…
Floquet engineering of point-gapped topological superconductors
Xiang Ji, Hao Geng, Naeem Akhtar +1
Non-Hermitian systems exhibit two distinct topological classifications based on their gap structure: line-gap and point-gap topologies. Although point-gap topology is intrinsic to…
Enhancement in temperature sensing of a reservoir by Kerr-nonlinear resonator
Naeem Akhtar, Jia-Xin Peng, Xiaosen Yang +1
The challenge of developing high-precision temperature sensors is an important issue that has recently received a lot of attention. In this work, we introduce an estimation techniq…
Tunable optical amplification and group delay in cavity magnomechanics
Abdul Wahab, Muqaddar Abbas, Xiaosen Yang +1
In this work, we theoretically investigate the controllable output probe transmission and group delay in a hybrid cavity magnomechanics (CMM) system. The setup comprises a gain (ac…
Enhanced second-order sideband generation and slow-fast light via coupled opto- and magnomechanical microspheres
Abdul Wahab, Muqaddar Abbas, Xiaosen Yang +2
In this research, we investigate second-order sideband generation (SSG) and slow-fast light using a hybrid system comprised of two coupled opto- and magnomechanical microspheres, n…
