Lightshow: a Python package for generating computational x-ray absorption spectroscopy input files
Matthew R. Carbone, Fanchen Meng, Christian Vorwerk +7
First-principles computational spectroscopy is a critical tool for interpreting experiment, performing structure refinement, and developing new physical understanding. Systematical…
Five-second coherence of a single spin with single-shot readout in silicon carbide
Christopher P. Anderson, Elena O. Glen, Cyrus Zeledon +11
An outstanding hurdle for defect spin qubits in silicon carbide (SiC) is single-shot readout - a deterministic measurement of the quantum state. Here, we demonstrate single-shot re…
Theoretical description of optical and X-ray absorption spectra of MgO including many-body effects
Vijaya Begum, Markus E. Gruner, Christian Vorwerk +2
Here we report the optical and x-ray absorption (XAS) spectra of the wide-band-gap oxide MgO using density functional theory (DFT) and many-body perturbation theory (MBPT). Our com…
Influence of Polymorphism on the Electronic Structure of GaO
Jack E. N. Swallow, Christian Vorwerk, Piero Mazzolini +21
The search for new wide band gap materials is intensifying to satisfy the need for more advanced and energy efficient power electronic devices. GaO has emerged as an altern…
Excitation Pathways in Resonant Inelastic X-Ray Scattering of Solids
Christian Vorwerk, Francesco Sottile, Claudia Draxl
We present a novel derivation of resonant inelastic x-ray scattering (RIXS) which yields an expression for the RIXS cross section in terms of emission pathways between intermediate…
High Performance Solution of Skew-symmetric Eigenvalue Problems with Applications in Solving the Bethe-Salpeter Eigenvalue Problem
Carolin Penke, Andreas Marek, Christian Vorwerk +2
We present a high-performance solver for dense skew-symmetric matrix eigenvalue problems. Our work is motivated by applications in computational quantum physics, where one solution…
