The Drude weight for the spin transport of the spin-1/2

Heisenberg

chain in the critical regime is evaluated exactly for finite temperatures. We

combine the thermodynamic Bethe ansatz with the functional relations of type

-system satisfie...

Mar 2019

A crossing probability for the critical four-state Potts model on the

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 ...

Sep 2018

We introduce generalizations of type

and

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...

Dec 2015

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...

Jul 2015

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...
