Knot Topology in Quantum Spin System
X. M. Yang, L. Jin, Z. Song
Knot theory provides a powerful tool for the understanding of topological matters in biology, chemistry, and physics. Here knot theory is introduced to describe topological phases…
Non-Hermitian phase transition and eigenstate localization induced by asymmetric coupling
P. Wang, L. Jin, Z. Song
We investigate a uniformly coupled non-Hermitian system with asymmetric coupling amplitude. The asymmetric coupling equals to a symmetric coupling threaded by an imaginary gauge fi…
Visualizing Topology of Real-Energy Gapless Phase Arising from Exceptional Point
X. M. Yang, P. Wang, L. Jin +1
The discovery of novel topological phase advances our knowledge of nature and stimulates the development of applications. In non-Hermitian topological systems, the topology of band…
Flat band induced by the interplay of synthetic magnetic flux and non-Hermiticity
L. Jin
A flat band is nondispersive and formed under destructive interference. Although flat bands are found in various Hermitian systems, to realize a flat band in non-Hermitian systems…
