The Drude weight for the spin transport of the spin-1/2 Tex Heisenberg
chain in the critical regime is evaluated exactly for finite temperatures. We
combine the thermodynamic Bethe ansatz with the functional relations of type
Tex-system satisfie...

A crossing probability for the critical four-state Potts model on the
Tex rectangle on the square lattice is numerically studied. The
crossing probability here denotes the probability that spin clusters cross from
one side of the boundary ...

We introduce generalizations of type Tex and Tex ice models which were
recently introduced by Ivanov and Brubaker-Bump-Chinta-Gunnells, and study in
detail the partition functions of the models by using the quantum inverse
scattering method. We co...

We review and present new studies on the relation between the partition
functions of integrable lattice models and symmetric polynomials, and its
combinatorial representation theory based on the correspondence, including our
work. In particular, w...

We examine and present new combinatorics for the Schur polynomials from the
viewpoint of quantum integrability. We introduce and analyze an integrable
six-vertex model which can be viewed as a certain degeneration model from a
t-deformed boson mod...

Ministry of Education, Culture, Sports, Science and Technology: Grants-in-Aid for Scientific Research(基盤研究(B))
Project Year: 2006 - 2009    Investigator(s): Minoru TAKAHASHI
・ Static correlation functions of one dimensional XXX and XXZ models at the ground state Before this project we already calculated 4-th neighbor correlation functions. We invented the generating functions method and could calculate fifth, sixth an...
