S-wave/spin-triplet order in superconductors without inversion symmetry: LiPdB and LiPtB
H. Q. Yuan, D. F. Agterberg, N. Hayashi +5
We investigate the order parameter of noncentrosymmetric superconductors LiPdB and LiPtB via the behavior of the penetration depth . The low-temperature penet…
Quasiparticle Dynamics in the Kondo Lattice Model at Half Filling
Simon Trebst, Hartmut Monien, Axel Grzesik +1
We study spectral properties of quasiparticles in the Kondo lattice model in one and two dimensions including the coherent quasiparticle dispersions, their spectral weights and the…
Basic Properties of a Vortex in a Noncentrosymmetric Superconductor
N. Hayashi, Y. Kato, P. A. Frigeri +2
We numerically study the vortex core structure in a noncentrosymmetric superconductor such as CePt3Si without mirror symmetry about the xy plane. A single vortex along the z axis a…
Theory for Inelastic Neutron Scattering in Orthorhombic High-Tc Superconductors
Andreas P. Schnyder, Dirk Manske, Christopher Mudry +1
Using a Fermi-liquid-based theory we calculate the in-plane anisotropy of the spin susceptibility for hole-doped high-T_c cuprates. Employing the two-dimensional one-band Hubbard m…
Magnetic domain formation in itinerant metamagnets
B. Binz, H. B. Braun, T. M. Rice +1
We examine the effects of long-range dipolar forces on metamagnetic transitions and generalize the theory of Condon domains to the case of an itinerant electron system undergoing a…
Slave-boson theory of the Mott transition in the two-band Hubbard model
A. Rüegg, M. Indergand, S. Pilgram +1
We apply the slave-boson approach of Kotliar and Ruckenstein to the two-band Hubbard model with an Ising like Hund's rule coupling and bands of different widths. On the mean-field…
