Symmetry of the superconducting order parameter in frustrated systems determined by the spatial anisotropy of spin correlations
B. J. Powell, Ross H. McKenzie
We study the resonating valence bond (RVB) theory of the Hubbard-Heisenberg model on the half-filled anisotropic triangular lattice. Varying the frustration changes the wavevector…
Comparison of the phase diagram of the half-filled layered organic superconductors with the phase diagram of the RVB theory of the Hubbard-Heisenberg model
B. J. Powell, Ross H. McKenzie
We present an resonating valence bond (RVB) theory of superconductivity for the Hubbard--Heisenberg model on an anisotropic triangular lattice. We show that these calculations are…
On the Relationship Between the Critical Temperature and the London Penetration Depth in Layered Organic Superconductors
B. J. Powell, Ross H. McKenzie
We present an analysis of previously published measurements of the London penetration depth of layered organic superconductors. The predictions of the BCS theory of superconductivi…
First-principle density-functional calculation of the Raman spectra of BEDT-TTF
K. Brake, B. J. Powell, R. H. McKenzie +2
We present a first-principles density-functional calculation for the Raman spectra of a neutral BEDT-TTF molecule. Our results are in excellent agreement with experimental results.…
The Dependence of the Superconducting Transition Temperature of Organic Molecular Crystals on Intrinsically Non-Magnetic Disorder: a Signature of either Unconventional Superconductivity or Novel Local Magnetic Moment Formation
B. J. Powell, Ross H. McKenzie
We give a theoretical analysis of published experimental studies of the effects of impurities and disorder on the superconducting transition temperature, T_c, of the organic molecu…
