AbdiarXiv·2025·10.48550/arxiv.2501.08055·arXiv:2501.08055AbstractWe investigate the electron spin dephasing time of negatively charged boron vacancies (VB centers) in hexagonal boron nitride by considering dipolar hyperfine interactions with the nuclear spin bath and spin-phonon interactions. Using a Holstein-Primakoff transformation for the spin bath and a Debye model for lattice phonons, we estimate that the Hahn-echo coherence time of the VB electron spin is approximately 30 µs at room temperature.Read more
