Query: Brownian motion of classical spins : Anomalous dissipation and
  generalized Langevin equation   In this work, we analyze the relaxation of a classical spin interacting with
a heat bath, starting from the fully dynamical Hamiltonian description. An
analogous problem in the framework of generalized Langevin equation (GLE) with
anomalous dissipation is analyzed in details. The Fokker-Planck equation
corresponding to GLE is derived and the concept of equilibrium probability
distribution is analyzed. In this process we have identified few difficulties
to obtain equilibrium distribution for the non-Markovian case and the remedy to
overcome this difficulty is also discussed.
