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…

Simulating bosonic Chern insulators in one-dimensional optical superlattices
Yu-Lian Chen, Guo-Qing Zhang, Dan-Wei Zhang +1
We study the topological properties of an extended Bose-Hubbard model with cyclically modulated hopping and on-site potential parameters, which can be realized with ultracold boson…
