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…
