Resumen:

A quantum?statistical binary gas mixture model consisting of positive?energy resonant bosonic Cooper electron pairs in chemical and thermal equilibrium with single unpaired electrons yields, via two?time retarded Green functions, an analytic expression for a dimensionlesSocoupling ?? and temperature T?dependent generalized energy gap Eg(?, T) in the single-electron spectrum. The new gap gives a reasonable description of overdoped. © 2011 by World Scientific Publishing Co. Pte. Ltd. All rights reserved.
