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…
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 origin of the difference in the superconducting critical temperatures of the beta_H and beta_L phases of (BEDT-TTF)_2I_3
B. J. Powell
Incommensurate lattice fluctuations are present in the beta_L phase (T_c = 1.5 K) of ET_2I_3 (where ET is BEDT-TTF - bis(ethylenedithio)tetrathiafulvalene) but are absent in the be…
The Behavior of a Triplet Superconductor in a Spin Only Magnetic Field
B. J. Powell, James F. Annett, B. L. Gyorffy
We investigate the order parameter of SrRuO in an exchange-only magnetic field. A Ginzburg-Landau symmetry analysis implies three possibilities: a pure He A phase, a $^…
