Dislocation-loop formation is a first-order phase transition
Xiaoya Chang, Arsalan Hashemi, Nima Ghafari Cherati +3
Dislocation loops are the elementary product of radiation damage in crystals, limiting reactor-component lifetimes, power-electronics reliability and the coherence of solid-state q…
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…
Magneto-optical properties of the neutral silicon-vacancy center in diamond under extreme isotropic strain fields
Meysam Mohseni, GergÅ Thiering, Adam Gali
The neutral silicon--vacancy (SiV) center in diamond combines inversion symmetry with optical emission, making it a robust quantum emitter resilient to stray electric fields.…
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…
Magneto-optical properties of Group-IV--vacancy centers in diamond upon hydrostatic pressure
Meysam Mohseni, Lukas Razinkovas, Vytautas Žalandauskas +2
In recent years, the negatively charged group-IV--vacancy defects in diamond, labeled as G4V(-) or G4V centers, have attracted significant attention in quantum information processi…
