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…

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…
Anisotropic longitudinal optical conductivities of tilted Dirac bands in 1T-MoS
Chao-Yang Tan, Chang-Xu Yan, Yong-Hong Zhao +2
1T-MoS exhibits valley-spin-polarized tilted Dirac bands in the presence of external vertical electric field and undergoes a topological phase transition between the t…
Crystalline geometries from fermionic vortex lattice with hyperscaling violation
Li-Ke Chen, Hong Guo, Fu-Wen Shu
We analytically consider the spontaneous formation of a fermionic crystalline geometry in a gravity background with Lifshitz scaling and/or hyperscaling violation. Fermionic vortex…
A holographic model of d-wave superconductor vortices with Lifshitz scaling
Hong Guo, Fu-Wen Shu, Jing-He Chen +2
We study analytically the -wave holographic superconductors with Lifshitz scaling in the presence of external magnetic field. The vortex lattice solutions of the model have also…
