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…
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…
RKKY interaction of magnetic impurities in Dirac and Weyl semimetals
Hao-Ran Chang, Jianhui Zhou, Shi-Xiong Wang +2
We theoretically study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between magnetic impurities in both Dirac and Weyl semimetals (SMs). We find that the internode process,…
Formation of holographic vortex in a rotating shell-shaped superfluid
Chang-Xu Yan, Hao-Ran Chang, Meng Gao +2
We investigate the holographic superfluid dynamics subjected to external rotation on a spherical geometry. Through a linear perturbation analysis, we identify several dynamically u…
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…
Plasmons in a two-dimensional nonsymmorphic nodal-line semimetal
Jin Cao, Hao-Ran Chang, Xiaolong Feng +2
Recent experiments have established a type of nonsymmorphic symmetry protected nodal lines in the family of two-dimensional (2D) composition tunable materials NbSiTe. Here,…
