Dephasing by a nonstationary classical intermittent noise
Dephasing by a nonstationary classical intermittent noise
We consider a phenomenological model for a $1∕{f}^{\ensuremath{\mu}}$ classical intermittent noise and study its effects on the dephasing of a two-level system. Within this model, the evolution of the relative phase between the $\ensuremath{\mid}\ifmmode\pm\else\textpm\fi{}⟩$ states is described as a continuous time random walk (CTRW). Using renewal theory, we find exact …
