Exceptional entanglement in non-Hermitian fermionic models
Wei-Zhu Yi, Yong-Ju Hai, Rong Xiao +1
Exotic singular objects, known as exceptional points, are ubiquitous in non-Hermitian physics. They might be spectral singularities in energy bands that produce anomalous effects a…
Non-Hermitian skin effect in a single trapped ion
Ziguang Lin, Yiheng Lin, Wei Yi
Non-Hermitian skin effect (NHSE) describes the exponential localization of all eigenstates toward boundaries in non-Hermitian systems, and has attracted intense research interest o…
Fate of entanglement in one-dimensional fermion liquid with coherent particle loss
Wei-Zhu Yi, Hao-Jie Lin, Ze-Xun Lin +1
Quantum many-body systems and quantum devices experience the detrimental effects of noise and particle losses, necessitating their treatment as open quantum systems or, in approxim…
Probing two-body exceptional points in open dissipative systems
Peize Ding, Wei Yi
We study two-body non-Hermitian physics in the context of an open dissipative system depicted by the Lindblad master equation. Adopting a minimal lattice model of a handful of inte…
Fate of Quantum Anomalies for 1d lattice chiral fermion with a simple non-Hermitian Hamiltonian
Wei-Qiang Chen, Yong-Shi Wu, Wenjie Xi +2
It is generally believed that the 1+1D model for a single chiral fermion does not exist by itself alone on lattice. The obstruction to such a lattice realization is the failure to…
Possible particle-hole instabilities in interacting type-II Weyl semimetals
Weizhu Yi, Qiu-Shi Wang, Rui Wang +1
Type II Weyl semimetal, a three dimensional gapless topological phase, has drawn enormous interest recently. These topological semimetals enjoy overtilted dispersion and Weyl nodes…
Driven-dissipative many-body pairing states for cold fermionic atoms in an optical lattice
W. Yi, S. Diehl, A. J. Daley +1
We discuss the preparation of many-body states of cold fermionic atoms in an optical lattice via controlled dissipative processes induced by coupling the system to a reservoir. Bas…
