On Bose-Einstein condensation in quasi-2D systems with applications to high Tc superconductivity II

Abstract

We calculate the number and energy densities of a quasi-2D Bose-Einstein gas constrained within a thin region of infinite extent but of finite width d. The BEC critical transition temperature then becomes an explicit function of d. We use this result to construct a model of high-Tc superconductivity in cuprates with a periodic layered atomic structure. The predicted behavior of the BEC Tc agrees with recent experimental findings in severely underdoped cuprates.
