Ultracold atomic lattice systems for simulating topological phases: A review
Bei-Bei Wang, Xiao-Dong Lin, Jinyi Zhang +1
Owing to rapid recent progress, ultracold atomic lattice systems for simulating topological phases are now at a pivotal stage, evolving from established paradigms into increasingly…
Proposal for realizing unpaired Weyl points in a three-dimensional periodically driven optical Raman lattice
Xiao-Dong Lin, Jinyi Zhang, Long Zhang
In static lattice systems, the Nielsen-Ninomiya theorem enforces the pairing of Weyl points with opposite chiralities, which precludes the chiral magnetic effect (CME) in equilibri…
Measuring topological invariants of even-dimensional line-gapped non-Hermitian systems through quench dynamics
Xiao-Dong Lin, Long Zhang
The accurate determination of non-Hermitian (NH) topological invariants plays a central role in the study of NH topological phases. In this work, we propose a general framework for…
Measuring Non-Hermitian Topological Invariants Directly from Quench Dynamics
Xiao-Dong Lin, Long Zhang
While non-Hermitian (NH) topological phases and phenomena have been observed across various quantum systems, directly measuring NH topological invariants remains a significant chal…
