Tomonaga-Luttinger parameters for doped Mott insulators
Satoshi Ejima, Florian Gebhard, Satoshi Nishimoto
The Tomonaga--Luttinger parameter determines the critical behavior in quasi one-dimensional correlated electron systems, e.g., the exponent for the density of states near…
Ring Exchange Mechanism for Triplet Superconductivity in a Two-Chain Hubbard Model: Possible Relevance to Bechgaard Salts
Y. Ohta, S. Nishimoto, T. Shirakawa +1
The density-matrix renormalization group method is used to study the ground state of the two-chain zigzag-bond Hubbard model at quarter filling. We show that, with a proper choice…
Phase Diagram of the ------ Model at Quarter Filling
Satoshi Ejima, Florian Gebhard, Satoshi Nishimoto +1
We examine the ground-state properties of the one-dimensional Hubbard model at quarter filling with Coulomb interactions between nearest-neighbors and next-nearest neighbors…
Density-matrix renormalisation group approach to quantum impurity problems
Satoshi Nishimoto, Eric Jeckelmann
A dynamic density-matrix renormalisation group approach to the spectral properties of quantum impurity problems is presented. The method is demonstrated on the spectral density of…
