AbstractWhen pairing correlations in a quasi two dimensional electron system induce a pseudogap in the single particle density of states, the specific heat must also contain a sizeable pair contribution. The theoretically calculated specific heat for such a system is compared to the experimental results of Loram and his collaborators for underdoped YBa_2Cu_3O_{6+x} and La_{2-x}Sr_{x}CuO_4 samples. The size and doping dependence of the extracted pseudogap energy scale for both materials is comparable to the values obtained from a variety of other experiments.

Review title: is it possible to consider the phase transition together with the pseudogap?

Comment: The most interesting thing in this article is the fact that electronic specific heat from single particles cannot reproduce the wide hump be [...]
