First-principles upper bounds on dark matter-electron scattering rates from condensed matter sum rules
Bradford A. Barker, Jay Epstein, Luke James +5
A wide variety of condensed matter systems are used or proposed as detectors to search for dark matter-electron scattering. In general, the scattering rate depends on detailed know…
Exchange-Driven Intermixing of Bulk and Topological Surface State by Chiral Excitons in Bi2Se3
Bowen Hou, Dan Wang, Bradford A. Barker +1
Topological surface states (TSS) in the prototypical topological insulator (TI) Bi2Se3 are frequently characterized using optical probes, but electron-hole interactions and their e…
Spin-flip Bethe-Salpeter equation approach for ground and excited states of open-shell molecules and defects in solids
Bradford A. Barker, David A. Strubbe
Open-shell systems such as magnetic molecules or defects with a triplet ground state are challenging to describe in electronic structure methods, but are of great interest for quan…
Fully relativistic /Bethe-Salpeter calculations in BerkeleyGW: implementation, symmetries, benchmarking, and performance
Bradford A. Barker, Jack Deslippe, Johannes Lischner +5
Computing the quasiparticle bandstructure and Bethe-Salpeter Equation (BSE) absorption spectra for materials with spin-orbit coupling has commonly been done by treating c…
The electronic structure of -HgS via calculations
Bradford A. Barker, Steven G. Louie
The electronic structure of the zincblende -HgS is not well understood. Previous first-principles calculations using fully-relativistic density functional theory and many-body p…
