Electronic specific heat in the pairing pseudogap regime
Electronic specific heat in the pairing pseudogap regime
When 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 sizable pair contribution. The theoretically calculated specific heat for such a system is compared to the experimental results of Loram and his collaborators for underdoped ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{6+x}$ …
