Interband optical conductivities in two-dimensional tilted Dirac bands revisited within the tight-binding model
Chao-Yang Tan, Jian-Tong Hou, Xin Chen +6
Within the framework of linear response theory, we theoretically investigated the interband longitudinal optical conductivities (LOCs) in two-dimensional (2D) tilted Dirac bands us…
Interband optical conductivity in two-dimensional semi-Dirac bands tilting along the quadratic dispersion
Xin Chen, Jian-Tong Hou, Long Liang +4
Two-dimensional (2D) semi-Dirac materials feature a unique anisotropic band structure characterized by quadratic dispersion along one spatial direction and linear dispersion along…
Longitudinal optical conductivities of tilted Weyl fermions in arbitrary dimensionality
Jian-Tong Hou, Peng Wang, Hong Guo +1
The unified form of longitudinal optical conductivities (LOCs) in the tilted Weyl fermions for arbitrary spatial dimensionality are analytically calculated and expressed in terms o…
Effects of spatial dimensionality and band tilting on the longitudinal optical conductivities in Dirac bands
Jian-Tong Hou, Chang-Xu Yan, Chao-Yang Tan +4
We report a unified theory based on linear response, for analyzing the longitudinal optical conductivity (LOC) of materials with tilted Dirac cones. Depending on the tilt parameter…
Signatures of Lifshitz transition in the optical conductivity of two-dimensional tilted Dirac materials
Chao-Yang Tan, Jian-Tong Hou, Chang-Xu Yan +2
Lifshitz transition is a kind of topological phase transition in which the Fermi surface is reconstructed. It can occur in the two-dimensional (2D) tilted Dirac materials when the…
