Non-perturbative approach for calculating the electrical conductivity of a liquid metal
Xiao-Wei Zhang, Haoran Chen, En-Ge Wang +2
We propose a non-perturbative approach to calculate the electrical conductivity of a liquid metal. Our approach is based on the Kubo formula and the theory of electro…
Phonon-mediated exciton relaxation in two-dimensional semiconductors: selection rules and relaxation pathways
Xiao-Wei Zhang, Kaichen Xie, En-Ge Wang +2
Exciton-phonon coupling (ExPC) is crucial for energy relaxation in semiconductors, yet the first-principles calculation of such coupling remains challenging, especially for low-dim…
The influence of high-energy local orbitals and electron-phonon interactions on the band gaps and optical spectra of hexagonal boron nitride
Tong Shen, Xiao-Wei Zhang, Honghui Shang +5
We report band diagram and optical absorption spectra of hexagonal boron nitride (-BN), focusing on unravelling how the completeness of basis set for calculat…
Ab initio investigation on the experimental observation of metallic hydrogen
Xiaowei Zhang, En-Ge Wang, Xin-Zheng Li
The optical spectra of hydrogen at 500 GPa were studied theoretically using a combination of \emph{ab initio} methods. Among the four most competitive structures, i.e. C2/c-2…
