Non-Hermitian quantum metrology, an emerging field at the intersection of quantum estimation and non-Hermitian physics, holds promise for revolutionizing precision …
Non-Hermitian Chern insulators differ from their Hermitian cousins in one key aspect: their edge spectra are incredibly rich and confounding. For example, even in the simple case …
Quantum parameter estimation with Hermitian systems has been applied in various fields, but there are relatively few results concerning non-Hermitian systems. Here, we study the …

We study the enhanced sensing of optomechanically induced nonlinearity (OMIN) in a cavity- waveguide coupled system. The Hamiltonian of the system is anti-PT symmetric, with the two …
We reveal the continuous change of information dynamics patterns in anyonic-PT symmetric systems that originates from the continuity of anyonic-PT symmetry. We find there are three …

Non-Hermitian (NH) physics has a close relationship with open and dissipative systems, attracting attentions increasingly. The conventional entropy based on the normalized …
Abstract Non-Hermitian (NH) Hamiltonians have long been used to describe a wide range of open or nonequilibrium quantum systems. The experimental realization of parity-time …
In recent times a large body of literature has been devoted to the study of non-Hermitian systems. The central idea behind such studies has been the Parity-Time [PT] symmetry and …
