We study the trimer state in a three-body system,where two of the atoms are subject to Rashba-type spin-orbit coupling and spin-dependent loss while interacting spin-selectively with the third atom.The short-time cond...

Non-Hermitian dynamics exhibits a wealth of surprising and potentially useful phenomena.However,it is typically realized by coupling a system with thermal reservoirs,which makes the system suffer from thermal fluctuat...

We investigate distinct non-Hermitian skin effects(NHSEs)in real and Fock spaces induced by the interplay between the Hilbert space fragmentation and multiple non-Hermitian pumping channels.Using an extended Hatano–N...
One of unique features of non-Hermitian systems is the extreme sensitive to their boundary conditions,e.g.,the emergence of non-Hermitian skin effect(NHSE)under the open boundary conditions,where most of bulk states b...

Non-Hermitian properties play an important role in topological acoustic systems,which can not only change the band topology but may also lead to novel applications such as non-Hermitian skin effect(NHSE).However,non-H...
In our study,we explore high-order exceptional points(EPs),which are crucial for enhancing the sensitivity of open physical systems to external changes.We utilize the Hilbert-Schmidt speed(HSS),a measure of quantum st...

The non-Hermitian skin effect is an iconic phenomenon characterized by the aggregation of eigenstates near the system boundaries in non-Hermitian systems.While extensively studied in one dimension,understanding the sk...
Quantum Fisher information is used to witness the quantum phase transition in a non-Hermitian trapped ion system with balanced gain and loss,from the viewpoint of quantum parameter estimation.We formulate a general no...

We give global structure of spectra of periodic non-Hermitian Jacobi operators by the discriminant and its stationary points. We also give necessary and sufficient conditions for real spectra and single interval spectra.
