Spectral Functions of the Uniform Electron Gas via Coupled-Cluster Theory and Comparison to the and Related Approximations
James McClain, Johannes Lischner, Thomas Watson +5
We use, for the first time, ab initio coupled-cluster theory to compute the spectral function of the uniform electron gas at a Wigner-Seitz radius of . The coupled-…
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…
First-principles theory of electron-spin fluctuation coupling and superconducting instabilities in iron selenide
Johannes Lischner, Timur Bazhirov, Allan H. MacDonald +2
We present first-principles calculations of the coupling of quasiparticles to spin fluctuations in iron selenide and discuss which types of superconducting instabilities this coupl…
