Variational Monte Carlo studies of a t-J model on an anisotropic triangular lattice
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +2
With the insulating phase of κ-(BEDT-TTF)_2X in mind, we study a t-J model on an anisotropic triangular lattice, where the hopping integral is t' in one of the three directions, us…
Variational Monte Carlo Studies of Pairing Symmetry for the t-J Model on a Triangular Lattice
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +2
As a model of a novel superconductor Na_xCoO_2\cdotyH_2O, a single-band t-J model on a triangular lattice is studied, using a variational Monte Carlo method. We calculate the energ…
Influence of magnetic impurities on charge transport in diffusive-normal-metal / superconductor junctions
T. Yokoyama, Y. Tanaka, A. A. Golubov +2
Charge transport in the diffusive normal metal (DN) / insulator / - and -wave superconductor junctions is studied in the presence of magnetic impurities in DN in the frame…
Suppression of the Persistent Spin Hall Current by Defect Scattering
Jun-ichiro Inoue, Gerrit E. W. Bauer, Laurens W. Molenkamp
We study the linear response spin Hall conductivity of a two-dimensional electron gas (2DEG) in the presence of the Rashba spin orbit interaction in the diffusive transport regime.…
