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,…
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…
Anomalous acoustic plasmons in two-dimensional over-tilted Dirac bands
Chang-Xu Yan, Furu Zhang, Chao-Yang Tan +3
The over-tilting of Dirac cones has led to various fascinating quantum phenomena. Here we find that two anomalous acoustic plasmons (AAPs) are dictated by the distinct geometry of…
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…
