Biorthogonal dynamical quantum phase transitions in non-Hermitian topological superconductors

Haoran Gu, Yubo Zhao, Siyuan Cheng +3

Dynamical quantum phase transitions in non-Hermitian systems pose fundamental challenges due to the intrinsic biorthogonality of their eigenstates. In this work, we extend a biorth…

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…

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…

Sub-shot-noise sensitivity via superpositions of two deformed kitten states

Naeem Akhtar, Xiaosen Yang, Jia-Xin Peng +3

In the present work we explore nonclassical effects in the phase space of two superposed kitten states induced by photon addition and subtraction operations applied in different se…

Compasslike states in a thermal reservoir and fragility of their nonclassical features

Naeem Akhtar, Xiaosen Yang, Muhammad Asjad +3

Superposed photon-added and photon-subtracted squeezed-vacuum states exhibit sub-Planck phase-space structures and metrological potential similar to the original compass states (su…

Non-Hermitian second-order topological superconductors

Xaing Ji, Wenchen Ding, Yuanping Chen +1

The topology of non-Hermitian systems is fundamentally changed by the non-Hermitian skin effect, which leads to the generalized bulk-boundary correspondence. Based on the non-Bloch…
