dc.descriptionIn recent years, researchers have discovered various excited states of electrons having an excited domain with a structural order different from the original one. We examine a dynamics of electron system and phonon system by using the time-dependent Hartree-Fock approximation. We examine time evolution with spin degree of freedom. We found a thermally excited paraelectric-to-ferroelectric crossover. The metastable state is spin pierls state. We also examine the Landau expansion of electron system at quarter-filled.
