Susceptibilities of Sr(Cu_(1-x)Zn_x)_2O_3 Studied by Quantum Monte Carlo Simulation
T. Miyazaki, M. Troyer, M. Ogata +2
The effects of non-magnetic impurities randomly doped into a two-leg Heisenberg spin ladder are investigated. Using the continuous time quantum Monte Carlo loop algorithm we calcul…
Resonating-Valence-Bond Ground-state of CaVO by the Gutzwiller-projected Schwinger-boson method
T. Miyazaki, D. Yoshioka
An antiferromagnetic Heisenberg model on a 1/5-depleted two-dimensional square-lattice, a model of CaVO, is investigated by variational Monte Carlo simulation. A prototype…
The effect of the Coulomb interaction on the mesoscopic persistent current
D. Yoshioka, H. Kato
The persistent current in three-dimensional mesoscopic rings is investigated numerically. The model is tight-binding one with random site-energies and interaction between electrons…
Anisotropic two-dimensional Heisenberg model by Schwinger-boson Gutzwiller projected method
T. Miyazaki, D. Yoshioka, M. Ogata
Two-dimensional Heisenberg model with anisotropic couplings in the and directions () is considered. The model is first solved in the Schwinger-boson mean-fiel…
Suppression of Persistent Currents in 1-D Disordered Rings by Coulomb Interaction
H. Kato, D. Yoshioka
Effects of Coulomb interaction on persistent currents in disordered one-dimensional rings are numerically investigated. First of all effectiveness of the Hartree-Fock approximation…
