Topological Anderson insulators in two-dimensional non-Hermitian disordered systems
Ling-Zhi Tang, Ling-Feng Zhang, Guo-Qing Zhang +1
The interplay among topology, disorder, and non-Hermiticity can induce some exotic topological and localization phenomena. Here we investigate this interplay in a two-dimensional n…
Statistically related many-body localization in the one-dimensional anyon Hubbard model
Guo-Qing Zhang, Dan-Wei Zhang, Zhi Li +2
Many-body localization (MBL) has been widely investigated for both fermions and bosons, it is, however, much less explored for anyons. Here we numerically calculate several physica…
Double exceptional links in a three-dimensional dissipative cold atomic gas
Peng He, Jia-Hao Fu, Dan-Wei Zhang +1
We explore the topological properties of non-Hermitian nodal-link semimetals with dissipative cold atoms in a three-dimensional optical lattice. We construct a two-band continuum m…
Factorisation of 3d Twisted Indices and the Geometry of Vortex Moduli Space
Samuel Crew, Nick Dorey, Daniel Zhang
We study the twisted indices of supersymmetric gauge theories in three dimensions on spatial with an angular momentum refinement. We demonstrate factorisati…
Doped holographic fermionic system
Wenjun Huang, Guoyang Fu, Dan Zhang +2
We construct a two-current model. It includes two gauge fields, which introduce the doping effect, and a neutral scalar field. And then we numerically construct an AdS black brane…
Skin superfluid, topological Mott insulators, and asymmetric dynamics in interacting non-Hermitian Aubry-Andre-Harper models
Dan-Wei Zhang, Yu-Lian Chen, Guo-Qing Zhang +3
Non-Hermitian quantum many-body systems are a fascinating subject to be explored. Using the generalized density matrix renormalisation group method and complementary exact diagonal…
