Enhanced emission from boron-vacancy center in rhombohedral boron nitride

Nasrin Estaji, Ismaeil Abdolhosseini Sarsari, Gergő Thiering, Ádám Gali

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 be prepared and read out optically, but in the common hexagonal form it emits …

Increased cyclicity of atomic transitions via coherent interference of decay paths

Eliza Cornell, Benjamin Pingault, Gergő Thiering, Neil Sinclair et autres

Optical readout is a fundamental tool in atomic state measurement, yet the fidelity of optical readout is frequently limited by imperfect photon collection. This can be mitigated when readout occurs on a cycling transition which continuously fluoresces under resonant excitation, thus increasing …

Photoelectric Imaging of the Optically Inactive Charge State of Silicon‐Vacancy Defects in Diamond

Ilia Chuprina, Gergő Thiering, Emilie Bourgeois, Anna Ermakova et autres

The investigation of optically active point defects in wide-bandgap semiconductors is driven by the development of solid-state quantum technologies. Such atom-like defects are used for the realization of quantum registers and quantum sensors. Reproducible engineering of even well-established defects with predictable properties …

Jahn-Teller-dynamics: Python package to determine vibronic interaction demonstrated on molecules and trigonal defect qubits

Balázs Tóth, Ádám Gali, Gergő Thiering

Trigonal solid-state defects are often subjects of spontaneous symmetry breaking driven by the E⊗e Jahn-Teller effect, reflecting strong electron-phonon coupling. These systems, particularly paramagnetic defect qubits in solids are central for quantum technology applications, where accurate knowledge of their fine-structure parameters – …

First-principles calculation of electron-phonon spectral functions for defects using phonon interpolation

Zoltan Santha, Gergő 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 phonon sidebands is often limited by the coarse vibrational spectrum of the largest defect supercells accessible by ab-initio electronic structure codes. In …

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC

Ali Tayefeh Younesi, Minh Tuan Luu, Christopher Linderälv, Vytautas Žalandauskas et autres

ABSTRACT Point defects in silicon carbide (SiC), particularly the negatively‐charged silicon vacancy () in 4H‐SiC, are leading candidates for scalable quantum technologies due to their favorable spin–optical properties and compatibility with industrial semiconductor fabrication processes. Comprehensive knowledge of a defect's electronic structure …
