Spin-polarization anisotropy included by mechanical bending in tungsten diselenide nanoribbons and tunable excitonic states
Hong Tang, Santosh Neupane, Li Yin +2
A WSe monolayer shows many interesting properties due to its spin-orbit coupling induced spin splitting in bands around the Fermi level and the spin-valley configuration. The o…

Understanding plasmon dispersion in nearly-free-electron metals: the relevance of exact constraints for novel exchange-correlation kernels within time-dependent density functional theory
Niraj K. Nepal, Santosh Adhikari, Bimal Neupane +3
Small-wavevector excitations in Coulomb-interacting systems can be decomposed into the high-energy collective longitudinal plasmon and the low-energy single-electron excitations. A…
