Competition between the Mott transition and the Anderson localization in 1D disordered interacting electron systems
Satoshi Fujimoto, Norio Kawakami
The competition between the Mott transition and the Anderson localization in one dimensional electron systems is studied based upon the bosonization and the renormalization group m…
Exact Critical Properties of the Multi-Component Interacting Fermion Model with Boundaries
S. Fujimoto, N. Kawakami
Exact critical properties of the one-dimensional SU() interacting fermion model with open boundaries are studied by using the Bethe ansatz method. We derive the surface critical…
Exact finite-size spectrum for the multi-channel Kondo model and Kac-Moody fusion rules
Satoshi Fujimoto, Norio Kawakami
The finite-size spectrum for the multi-channel Kondo model is derived analytically from the exact solution, by mapping the nontrivial Z part of the Kondo scattering into that…
Exact Critical Exponents for Pseudo-Particles in the Kondo Problem
S. Fujimoto, N. Kawakami, S. -K. Yang
Exact critical exponents of the Green functions for pseudo-fermions and slave bosons in the SU() Anderson model with are obtained by using the Bethe ansatz…
Weak-Coupling Approach to Hole-Doped S=1 Haldane Systems
S. Fujimoto, N. Kawakami
As a weak-coupling analogue of hole-doped Haldane systems, we study two models for coupled chains via Hund coupling; coupled Hubbard chains, and a Hubbard chain coupled with…
Bosonization approach to the one-dimensional Kondo lattice model
S. Fujimoto, N. Kawakami
The one-dimensional Kondo lattice model is investigated by using bosonization techniques and conformal field theory. In the half-filled band, the charge and spin gaps open for the…
