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…
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…
