High-Performance Near-Infrared Quantum Emission from Color Centers in hBN
Sean Doan, Sahil D. Patel, Yilin Chen +9
Color centers hosted in hexagonal boron nitride have emerged as a highly promising platform for single-photon emission and spin-photon technologies relevant to quantum communicatio…
Resonant states and nuclear dynamics in solid-state systems: the case of silicon-hydrogen bond dissociation
Woncheol Lee, Mark E. Turiansky, Dominic Waldhör +3
Bond breaking in the presence of highly energetic carriers is central to many important phenomena in physics and chemistry, including radiation damage, hot-carrier degradation, act…
A CN complex as an alternative to the T center in Si
J. K. Nangoi, M. E. Turiansky, C. G. Van de Walle
We present a first-principles study of a carbon-nitrogen (CN) impurity complex in silicon as an isoelectronic alternative to the T center [(CCH)]. The latter has been…
Giant Isotope Effect on the Excited-State Lifetime and Emission Efficiency of the Silicon T Centre
Moein Kazemi, Mehdi Keshavarz, Mark E. Turiansky +5
Efficient single-photon emitters are desirable for quantum technologies including quantum networks and photonic quantum computers. We investigate the T centre, a telecommunications…
Machine Learning Phonon Spectra for Fast and Accurate Optical Lineshapes of Defects
Mark E. Turiansky, John L. Lyons, Noam Bernstein
The optical properties of defects in solids produce rich physics, from gemstone coloration to single-photon emission for quantum networks. Essential to describing optical transitio…
Approximate Excited-State Potential Energy Surfaces for Defects in Solids
Mark E. Turiansky, John L. Lyons
A description of electron-phonon coupling at a defect or impurity is essential to characterizing and harnessing its functionality for a particular application. Electron-phonon coup…
Impact of Absorption due to Zero-Field Splitting on Loss in Dielectrics: A Case Study in Sapphire
Mark E. Turiansky, Chris G. Van de Walle
The coherence times of superconducting qubits are limited by loss mechanisms, whose microscopic origins have remained elusive. We propose a mechanism caused by transitions between…
Carbon in GaN as a nonradiative recombination center
Fangzhou Zhao, Hongyi Guan, Mark E. Turiansky +1
Trap-assisted nonradiative recombination has been shown to limit the efficiency of optoelectronic devices. While substitutional carbon () has been suggested to be a n…
