Topological Anderson insulators with different bulk states in quasiperiodic chains
Ling-Zhi Tang, Shu-Na Liu, Guo-Qing Zhang +1
We investigate the topology and localization of one-dimensional Hermitian and non-Hermitian Su-Schrieffer-Heeger chains with quasiperiodic hopping modulations. In the Hermitian cas…
Topological Anderson insulators in two-dimensional non-Hermitian disordered systems
Ling-Zhi Tang, Ling-Feng Zhang, Guo-Qing Zhang +1
The interplay among topology, disorder, and non-Hermiticity can induce some exotic topological and localization phenomena. Here we investigate this interplay in a two-dimensional n…
Double exceptional links in a three-dimensional dissipative cold atomic gas
Peng He, Jia-Hao Fu, Dan-Wei Zhang +1
We explore the topological properties of non-Hermitian nodal-link semimetals with dissipative cold atoms in a three-dimensional optical lattice. We construct a two-band continuum m…
Observation of coherent oscillation in single-passage Landau-Zener transitions
Guozhu Sun, Xueda Wen, Ming Gong +6
Landau-Zener transition (LZT) has been explored in a variety of physical systems for coherent population transfer between different quantum states. In recent years, there have been…
