Оne-particle spectrum and phase transition in ionic Pauli conductor

I.V. Stasyuk
I.R. Dulepa

Microscopic simple noninteracting model for the description of the energy spectrum of ion subsystem in Pauli ionic conductor is considered. Phase diagram of model is obtained with taking into account the possibility of transition into phase, that include "condensate", in middle field approximation. The temperature dependence of ionic hopping parameter conditioned it thermal activation is took into account too. The one-particle spectrum is calculated in random phase approximation. The frequency dependence of the density of states in different phases are investigated in wide range of temperature in example of quasi-one-dimensional system.
