Low-temperature Lanczos method for strongly correlated systems

Finite-temperature Simulation Based on the Lanczos Algorithm for Low-dimensional Strongly Correlated Electron Systems; High-temperature Superconducting Cuprates

The Lanczos algorithm is applied to calculate some finite-temperature physical quantities, as well as the ground-state ones. We introduce the finite-temperature Lanczos algorithm and apply it for some current problems in the low-dimensional strongly correlated electron systems; the charge stripe, the pseudogap and phonon-induced anomalous ARPES spectrum in the high-Tc superconducting cuprates.

High Temperature Superconductivity in Strongly Correlated Electronic Systems

In this paper we give a selective review of our work on the role of electron correlation in the theory of high temperature superconductivity. The question of how electronic repulsions might give rise to off-diagonal long range order (ODLRO) in high temperature superconductors is currently one of the key questions in the theory of condensed matter. This paper argues that the key to understanding...

Basis functions for strongly correlated Fermi systems

Abstract A general method to construct basis functions for fermionic systems which account for the SU(2) symmetry and for the translational invariance of the Hamiltonian is presented. The method does not depend on the dimensionality of the system and it appears as a natural generalization of the Bethe Ansatz to the case of non integrable systems. As an example we present the block diagonalizati...
