Аннотация:It was shown that the Coulomb interaction between electrons of “active” (resonance) pairs plays
a major role in a wide frequency range. Therefore, the conventional approach to the calculation of the superlinearity of the frequency dependence of ac conductivity, based on the singleparticle density of states with a Coulomb gap, is inapplicable to the calculation of highfrequency phononless conductivity. The observed superlinearity of the frequency dependence of the phononless hopping conductivity can manifest itself immediately in the region of the crossover from the linear to quadratic frequency dependence of the conductivity.
