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…
Interplay of non-Hermitian skin effects and Anderson localization in non-reciprocal quasiperiodic lattices
Hui Jiang, Li-Jun Lang, Chao Yang +2
Non-Hermiticity from non-reciprocal hoppings has been shown recently to demonstrate the non-Hermitian skin effect (NHSE) under open boundary conditions (OBCs). Here we study the in…
Emergent Macroscopic Nonreciprocity from Identical Active Particles via Spontaneous Symmetry Breaking
Wei-Chen Guo, Zuo Wang, Pei-Fang Wu +3
Nonreciprocity is known to generate a wide range of exotic phenomena in multi-species many-body systems, where different species influence one another through couplings that violat…
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…
Nodal Brillouin Zone Boundary from Folding a Chern Insulator
Li-Jun Lang, Shao-Liang Zhang, Qi Zhou
Chern insulator is a building block of many topological quantum matters, ranging from quantum spin Hall insulators to fractional Chern insulators. Here, we discuss a new type of in…
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…
