Disorder-Induced Entanglement Phase Transitions in Non-Hermitian Systems with Skin Effects
Kai Li, Ze-Chuan Liu, Yong Xu
Non-Hermitian dynamics is ubiquitous in various physical systems. While recent study shows that such a dynamics leads to an area-law scaling of the entanglement entropy due to the…
Topological Quantum Phase Transitions in Metallic Shiba Lattices
Ning Dai, Kai Li, Yan-Bin Yang +1
Shiba bands formed by overlapping Yu-Shiba-Rusinov subgap states in magnetic impurities on a superconductor play an important role in topological superconductors. Here, we theoreti…
Non-Hermitian Absorption Spectroscopy
Kai Li, Yong Xu
While non-Hermitian Hamiltonians have been experimentally realized in cold atom systems, it remains an outstanding open question of how to experimentally measure their complex ener…
Symmetry-Protected Topological Phases in a Rydberg Glass
Kai Li, Jiong-Hao Wang, Yan-Bin Yang +1
Recent theoretical studies predict that structural disorder, serving as a bridge connecting a crystalline material to an amorphous material, can induce a topological insulator from…
Higher-order Topological Anderson Insulators
Yan-Bin Yang, Kai Li, L. -M. Duan +1
We study disorder effects in a two-dimensional system with chiral symmetry and find that disorder can induce a quadrupole topological insulating phase (a higher-order topological p…
Topological Insulators beyond Energy Band Characterization
Yan-Bin Yang, Kai Li, Yong Xu
Topological phases of matter are generally characterized by topological properties of energy bands of a system. Their transitions under preserved symmetries occur through closing a…
