Optical properties of neutral F centers in bulk MgO with density matrix embedding

S Verma, A Mitra, Y Jin, S Haldar… - The Journal of …, 2023 - ACS Publications
The optical spectra of neutral oxygen vacancies (F0 centers) in the bulk MgO lattice are
investigated using density matrix embedding theory. The impurity Hamiltonian is solved with …

Decoherence of solid-state spin qubits: a computational perspective

M Onizhuk, G Galli - arXiv preprint arXiv:2405.18535, 2024 - arxiv.org
The usefulness of solid-state spins in quantum technologies depends on how long they can
remain in a coherent superposition of quantum states. This Colloquium discusses how first …
