Robust D-wave Pairing Correlations in a Hole-Doped Spin-Fermion Model for Cuprates

M. Moraghebi, S. Yunoki, A. Moreo

Pairing Correlations are studied numerically in the hole-doped spin-fermion model for cuprates. Simulations performed on up to 12x12 clusters provide robust indications of D-wave s…

Qualitative understanding of the sign of t' asymmetry in the extended t-J Model and relevance for pairing properties

G. B. Martins, J. C. Xavier, L. Arrachea +1

Numerical calculations illustrate the effect of the sign of the next nearest-neighbor hopping term t' on the 2-hole properties of the t-t'-J model. Working mainly on 2-leg ladders,…

Superconductivity in the Correlated Pyrochlore Cd_2Re_2O_7

R. Jin, J. He, S. McCall +3

We report the observation of superconductivity in high-quality CdReO single crystals with room-temperature pyrochlore structure. Resistivity and ac susceptibility measu…

Experimental observation of Frohlich superconductivity in high magnetic fields

N. Harrison, C. H. Mielke, J. Singleton +2

Resistivity and irreversible magnetisation data taken within the high-magnetic-field CDWx phase of the quasi-two-dimensional organic metal alpha-(BEDT-TTF)2KHg(SCN)4 are shown to b…

Superconducting 2D system with lifted spin degeneracy: Mixed singlet-triplet state

Lev P. Gor'kov, Emmanuel I. Rashba

Motivated by recent experimental findings, we have developed a theory of the superconducting state for 2D metals without inversion symmetry modeling the geometry of a surface super…
