First-principles calculation of electron-phonon spectral functions for defects using phonon interpolation
Zoltan Santha, Gergo Thiering
Point defects in wide-band-gap semiconductors exhibit optical spectra strongly shaped by electron-phonon coupling, but direct first-principles calculation of the corresponding phon…
Enhanced Emission from Boron-Vacancy Center in Rhombohedral Boron Nitride
Nasrin Estaji, Ismaeil Abdolhosseini Sarsari, GergÅ Thiering +1
Boron nitride is a layered crystal whose properties depend on how its atomic sheets are stacked. Its negatively charged boron vacancy is a well-established magnetic defect that can…
Unraveling the electronic structure of silicon vacancy centers in 4H-SiC
Ali Tayefeh Younesi, Minh Tuan Luu, Christopher Linderälv +7
Point defects in silicon carbide (SiC), particularly the negatively-charged silicon vacancy () in 4H-SiC, are leading candidates for scalable quantum technolog…
Exe.py: Ab initio fine structure parameters for trigonal defect qubits within the Ee Jahn-Teller case
Balazs Toth, Adam Gali, Gergo Thiering
Trigonal solid-state defects are often subjects of spontaneous symmetry breaking driven by the Jahn-Teller effect, reflecting strong electron-phonon coupling. These sy…
Spin-Phonon Relaxation of Boron-Vacancy Centers in Two-Dimensional Boron Nitride Polytypes
Nasrin Estaji, Ismaeil Abdolhosseini Sarsari, GergÅ Thiering +1
Two-dimensional (2D) materials hosting color centers and spin defects are emerging as key platforms for quantum technologies. However, the impact of reduced dimensionality on the s…
Nuclear spin relaxation in solid state defect quantum bits via electron-phonon coupling in their optical excited state
GergÅ Thiering, Adam Gali
Optically accessible solid state defect spins serve as a primary platform for quantum information processing, where precise control of the electron spin and ancillary nuclear spins…
