Non-Hermitian dynamics, as observed in photonic, atomic, electrical and optomechanical platforms, holds great potential for sensing applications and signal processing. Recently, fully tuneable non-reciprocal optical interaction has been demonstrated between levitated nanoparticles. Here we use this tunability...
A model system for the injection of fermionic particles from filled source sites into an empty chain is investigated. The ensuing dynamics for Hermitian as well as for non-Hermitian time evolution, where the particles cannot return to the bath sites (quantum ratchet), is studied. A non-...
Many-body localized phases retain memory of their initial conditions in disordered interacting systems with unitary dynamics. The stability of the localized phase due to the breakdown of unitarity is of relevance to experiment in the presence of dissipat
Periodically driven non-Hermitian quantum systems have become the center of interest in recent years due to their rich physical phenomena. In this work, we
Non-Hermitian dynamics is ubiquitous in various physical systems. While recent study shows that such a dynamics leads to an area-law scaling of the entangl... K Li,ZC Liu,Y Xu 被引量: 0发表: 2023年 The Deconfinement Phase Transition in One-Flavour QCD We present a study of the deconfi...
We present a simple non-Hermitian model to describe the phenomenon of asymmetric tunneling between two energy-degenerate sites coupled by a non-reciprocal interaction without dissipation. The system was described using a biorthogonal family of energy eigenvectors, the dynamics of the system was determine...
We investigated the dynamics of quantum Fisher information for a two-level system controlled by a non-Hermitian operation under the depolarization, and the non-Hermitian operation is described by a special Hamiltonian in which both the \mathcal {PT}-symmetric zone and the \mathcal {PT}-symmetry...
The non-Hermitian dynamics in the PMH system enhance anti-damping, thereby redefining dissipation mechanisms and establishing the optical conditions necessary for the emergence of NRI, as interpreted through an analytical circuit model that connects NRI with the non-Hermitian aspects of PMH systems. ...
