Entanglement renormalization of thermofield double states
Cheng-Ju Lin, Zhi Li, Timothy H. Hsieh
Entanglement renormalization is a method for coarse-graining a quantum state in real space, with the multi-scale entanglement renormalization ansatz (MERA) as a notable example. We…
Quantum phase transition in a non-Hermitian XY spin chain with global complex transverse field
Yu-Guo Liu, Lu Xu, Zhi Li
In this work, we investigate the quantum phase transition in a non-Hermitian XY spin chain. The phase diagram shows that the critical points of Ising phase transition expand into a…
Tensor monopoles and negative magnetoresistance effect in optical lattices
Hai-Tao Ding, Yan-Qing Zhu, Zhi Li +1
We propose that a kind of four-dimensional (4D) Hamiltonians, which host tensor monopoles related to quantum metric tensor in even dimensions, can be simulated by ultracold atoms i…
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…
Nonlinear Bloch-Zener oscillations for Bose-Einstein condensates in a Lieb optical lattice
Peng He, Zhi Li
We investigate Bloch-Zener oscillations and mean-field Bloch bands of a Bose-Einstein condensate (BEC) in a Lieb optical lattice. We find that the atomic interaction will break the…
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…
