Friedel oscillations in the one-dimensional Kondo-lattice model
N. Shibata, K. Ueda, T. Nishino +1
The paramagnetic metallic phase of the one-dimensional Kondo lattice model is studied by the density-matrix renormalization- group method. We observe charge and spin Friedel oscill…
Spin and charge gaps in the one-dimensional Kondo-lattice model with Coulomb interaction between conduction electrons
N. Shibata, T. Nishino, K. Ueda +1
The density-matrix renormalization-group method is applied to the one-dimensional Kondo-lattice model with the Coulomb interaction between the conduction electrons. The spin and ch…
Origin of Magic Angular Momentum in a Quantum Dot under Strong Magnetic Field
Taku Seki, Yoshio Kuramoto, Tomotoshi Nishino
This paper investigates origin of the extra stability associated with particular values (magic numbers) of the total angular momentum of electrons in a quantum dot under strong mag…
Numerical Renormalization Group at Criticality
T. Nishino, K. Okunishi, M. Kikuchi
We apply a recently developed numerical renormalization group, the corner-transfer-matrix renormalization group (CTMRG), to 2D classical lattice models at their critical temperatur…
Product Wave Function Renormalization Group Method
T. Nishino, K. Okunishi
The authors propose a fast numerical renormalization group method --- the product wave function renormalization group (PWFRG) method --- for 1D quantum lattice models and 2D classi…
Density Matrix Renormalization Group Method for 2D Classical Models
Tomotoshi Nishino
The density matrix renormalization group (DMRG) method is applied to the interaction round a face (IRF) model. When the transfer matrix is asymmetric, singular-value decomposition…
