Magnetic-field dependence of spin-phonon relaxation and dephasing due to g-factor fluctuations from first principles

Joshua Quinton, Mayada Fadel, Junqing Xu +4

The electron spin decay lifetime in materials can be characterized by relaxation (T1) and irreversible (T2) and reversible (T2*) decoherence processes. Their interplay leads to a c…
