, meV, is the energy of an optical phonon; is the critical temperature of the transition, is the latent heat of the transition from condensate to supracondensate state; is the jump in heat capacity during SC transition, ; is the heat capacity in the SC phase at the critical point; , . The calculations are carried out for the concentration of TI-bipolarons and the effective mass of a band electron . The table also lists the values of concentrations of TI-bipolarons for HTSC , based on the experimental value of the transition temperature = 93K (Section 6). |
