Many-Body Dynamics and Decoherence of the <i>XXZ</i> Central Spin Model in External Magnetic Field
The many-body dynamics of an electron spin−1/2 qubit coupled to a bath of nuclear spins by hyperfine interactions, as described by the central spin model in two kinds of external field, are studied in this paper. In a completely polarized bath, we use the state recurrence method to obtain...
