Nuclear spin polaron-formation: anisotropy effects and quantum phase transition
Iris Kleinjohann, Andreas Fischer, Mikhail M. Glazov +1
We study theoretically the formation of the nuclear-spin polaron state in semiconductor nanosystems within the Lindblad equation approach. To this end, we derive a general Lindblad…

Kinetic approach to the nuclear-spin polaron formation
Andreas Fischer, Iris Kleinjohann, Frithjof B. Anders +1
Under optical cooling of nuclei, a strongly correlated nuclear-spin polaron state can form in semiconductor nanostructures with localized charge carriers due to the strong hyperfin…

Magnetic field dependence of the electron spin revival amplitude in periodically pulsed quantum dots
Iris Kleinjohann, Eiko Evers, Philipp Schering +4
Periodic laser pulsing of singly charged semiconductor quantum dots in an external magnetic field leads to a synchronization of the spin dynamics with the optical excitation. The p…
