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.17 pages, 8 figuresMaterials ScienceStatistical Mechanicstext
