Distributed latent heat of the phase transitions in low-dimensional conductors

A simple consideration demonstrates that if the temperature of a second-order phase transition is suppressed by fluctuations, the dominating effect at the transition is a maximum, but not a jump of specific heat, cp. One can attribute a certain value of latent heat to the transition; an estimate of the "latent heat" is proposed and compared with the behavior of cp and of thermal expansion at the Peierls and superconducting transitions.
