Entanglement spectrum and entropy in topological non-Hermitian systems and non-unitary conformal field theories
Po-Yao Chang, Jhih-Shih You, Xueda Wen +1
We propose a method of computing and studying entanglement quantities in non-Hermitian systems by use of a biorthogonal basis. We find that the entanglement spectrum characterizes…

Dirac fermions and flat bands in the ideal kagome metal FeSn
Mingu Kang, Linda Ye, Shiang Fang +19
The kagome lattice based on 3d transition metals is a versatile platform for novel topological phases hosting symmetry-protected electronic excitations and exotic magnetic ground s…
