Pairing Fluctuation Theory of Superconducting Properties in Underdoped to Overdoped Cuprates
Pairing Fluctuation Theory of Superconducting Properties in Underdoped to Overdoped Cuprates
We propose a theoretical description of the superconducting state of under- to overdoped cuprates, based on the short coherence length of these materials and the associated strong pairing fluctuations. The calculated ${T}_{c}$ and the zero temperature excitation gap $\ensuremath{\Delta}(0)$, as a function of hole concentration $x$, are in semiquantitative agreement …
