Low-lying excitations of the three-leg spin tube using the density-matrix renormalization group method
S. Nishimoto, M. Arikawa
Using the (dynamical) density-matrix renormalization group method, we study the low-energy physics of three-leg antiferromagnetic Heisenberg model where the periodic boundary condi…

Superconductivity in a model of two Hubbard chains coupled with ferromagnetic exchange interaction
T. Shirakawa, S. Nishimoto, Y. Ohta
We study the ground-state properties of the double-chain Hubbard model coupled with ferromagnetic exchange interaction by using the weak-coupling theory, density-matrix renormaliza…
