Nonlinear Fokker-Planck equation for nonlocal and nonconservative model   Hamiltonians: symplectic integration and application to metastable systems
  Kinetics of metastable systems modeled by Hamiltonians containing nonlocal and nonconservative terms is reproduced by the Fokker-Planck and imaginary time Schrodinger equation scheme with subsequent symplectic integration. Example solutions for ergodicity breaking in ferroelectrics reassure the H-theorem of global stability [M. Shiino, Phys. Rev. A, Vol 36, pp. 2393-2411 (1987)] and reproduce spatially extended polarization response in time-dependent external fields.
