Pairing Fluctuation Theory of Superconducting Properties in Underdoped to Overdoped Cuprates
Qijin Chen, Ioan Kosztin, Boldizsar Janko +1
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…
On the Relationship Between the Pseudo- and Superconducting Gaps: Effects of Residual Pairing Correlations Below Tc
Ioan Kosztin, Qijin Chen, Boldizsar Janko +1
The existence of a normal state spectral gap in underdoped cuprates raises important questions about the associated superconducting phase. For example, how does this pseudogap evol…
Pairing Correlations and the Pseudo-Gap State: Application of the Pairing Approximation Theory
Jiri Maly, Boldizsar Janko, K. Levin
We investigate the pseudogap onset temperature , the superconducting transition temperature and the general nature of the pseudogap phase using a diagrammatic BCS-Bose E…
Superconducting transitions from the pseudogap state: d-wave symmetry, lattice, and low-dimensional effects
Qijin Chen, Ioan Kosztin, Boldizsar Janko +1
We investigate the behavior of the superconducting transition temperature within a previously developed BCS-Bose Einstein crossover picture. This picture, based on a decoupling sch…
