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…
Creating Weyl nodes and controlling their energy by magnetization rotation
Madhav Prasad Ghimire, Jorge I. Facio, Jhih-Shih You +6
As they do not rely on the presence of any crystal symmetry, Weyl nodes are robust topological features of an electronic structure that can occur at any momentum and energy. Acting…
Topological Nonlinear Anomalous Nersnt Effect in Strained Transition Metal Dichalcogenides
Xiao-Qin Yu, Zhen-Gang Zhu, Jhih-Shih You +2
We theoretically analyze the non-linear anomalous Nernst effect as the second-order response of temperature gradient by using the semiclassical framework of electron dynamics. We f…
