Non-Markovian spin relaxation model applied to point defect qubit systems

Controllable, partially isolated few level systems in semiconductors have
recently gained multidisciplinary attention due to their widespread
nanoscale sensing and quantum technology applications. Quantitative
simulation of the dynamics and related applications of such systems is a
challenging theoretical task that requires faithful description not only of
the few-level systems but also of the local environment. I will report on a
method that can describe relevant relaxation processes induced by a dilute
bath of nuclear and electron spins. The method utilizes an extended
Lindblad equation in the framework of cluster approximation of a central
spin system. Furthermore, I will demonstrate that the proposed method can
accurately describe the T1 time of an exemplary solid-state point defect
qubit system, the NV center in diamond, at various external fields.

Minden érdeklődőt szeretettel várunk.
