Satellite Band Structure in Silicon Caused by Electron-Plasmon Coupling
Johannes Lischner, G. K. Palsson, Derek Vigil-Fowler +5
We report the first angle-resolved photoemission measurement of the wave-vector dependent plasmon satellite structure of a three-dimensional solid, crystalline silicon. In sharp co…
Numerical integration for ab initio many-electron self energy calculations within the GW approximation
Fang Liu, Lin Lin, Derek Vigil-Fowler +8
We present a numerical integration scheme for evaluating the convolution of a Green's function with a screened Coulomb potential on the real axis in the GW approximation of the sel…
Satellite structures in the spectral functions of semiconductor quantum well two-dimensional electron gases: a GW plus cumulant study
Johannes Lischner, Derek Vigil-Fowler, Steven G. Louie
We present theoretical calculations for the spectral functions and single-particle densities of states of the two-dimensional electron gas in semiconductor quantum wells at differe…
Physical origin of satellite in photoemission of doped graphene: An ab-initio GW plus cumulant study
Johannes Lischner, Derek Vigil-Fowler, Steven G. Louie
We calculate the photoemission spectra of suspended and epitaxial doped graphene using an ab initio cumulant expansion of the Green's function based on the GW self-energy. Our resu…
