Query: Spin dynamics of a confined electron interacting with magnetic or
  nuclear spins: A semiclassical approach   A physically transparent and mathematically simple semiclassical model is
employed to examine dynamics in the central-spin problem. The results reproduce
a number of previous findings obtained by various quantum approaches and, at
the same time, provide information on the electron spin dynamics and Berry's
phase effects over a wider range of experimentally relevant parameters than
available previously. This development is relevant to dynamics of bound
magnetic polarons and spin dephasing of an electron trapped by an impurity or a
quantum dot, and coupled by a contact interaction to neighboring localized
magnetic impurities or nuclear spins. Furthermore, it substantiates the
applicability of semiclassical models to simulate dynamic properties of
spintronic nanostructures with a mesoscopic number of spins.
