Measurement-induced integer families of critical dynamical scaling in quantum many-body systems
Zuo Wang, Shi-Liang Zhu, Li-Jun Lang +1
A quantum many-body system can undergo transitions in the presence of continuous measurement. In this work, we find that a generic class of critical dynamical scaling behavior can…
Gain/loss effects on spin-orbit coupled ultracold atoms in two-dimensional optical lattices
Zhi-Cong Xu, Ziyu Zhou, Enhong Cheng +2
Due to the fundamental position of spin-orbit coupled ultracold atoms in the simulation of topological insulators, the gain/loss effects on these systems should be evaluated when c…
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…
Weyl points and topological nodal superfluids in a face-centered cubic optical lattice
Li-Jun Lang, Shao-Liang Zhang, K. T. Law +1
We point out that a face-centered cubic (FCC) optical lattice, which can be realised by a simple scheme using three lasers, provides one a highly controllable platform for creating…
Chiral d-wave superfluid in periodically driven lattices
Shao-Liang Zhang, Li-Jun Lang, Qi Zhou
Chiral d-wave superfluid is a preliminary example of topological matters that intrinsically encodes interaction effects. It exhibits fascinating properties including a finite Chern…
Topologically protected mid-gap states induced by impurity in one-dimensional superlattices
Li-Jun Lang, Shu Chen
Based on the discovery of the nontrivial topology of one-dimensional superlattices, we show that midgap states will emerge in such systems induced by a single on-site impurity. Bes…
Edge states and topological phases in one-dimensional optical superlattices
Li-Jun Lang, Xiaoming Cai, Shu Chen
We show that one-dimensional quasi-periodic optical lattice systems can exhibit edge states and topological phases which are generally believed to appear in two-dimensional systems…
