Correlation length of the 1D Hubbard Model at half-filling : equal-time one-particle Green's function
Y. Umeno, M. Shiroishi, A. Kluemper
The asymptotics of the equal-time one-particle Green's function for the half-filled one-dimensional Hubbard model is studied at finite temperature. We calculate its correlation len…
Fermionic R-Operator and Algebraic Structure of 1D Hubbard Model: Its application to quantum transfer matrix
Yukiko Umeno
The algebraic structure of the 1D Hubbard model is studied by means of the fermionic R-operator approach. This approach treats the fermion models directly in the framework of the q…
Fermionic R-operator approach for the small-polaron model with open boundary condition
Yukiko Umeno, Heng Fan, Miki Wadati
Exact integrability and algebraic Bethe ansatz of the small-polaron model with the open boundary condition are discussed in the framework of the quantum inverse scattering method (…
Commuting quantum transfer matrix approach to intrinsic Fermion system: Correlation length of a spinless Fermion model
Kazumitsu Sakai, Masahiro Shiroishi, Junji Suzuki +1
The quantum transfer matrix (QTM) approach to integrable lattice Fermion systems is presented. As a simple case we treat the spinless Fermion model with repulsive interaction in cr…
Fermionic R-Operator and Integrability of the One-Dimensional Hubbard Model
Yukiko Umeno, Masahiro Shiroishi, Miki Wadati
We propose a new type of the Yang-Baxter equation (YBE) and the decorated Yang-Baxter equation (DYBE). Those relations for the fermionic R-operator were introduced recently as a to…
Fermionic R-Operator for the Fermion Chain Model
Yukiko Umeno, Masahiro Shiroishi, Miki Wadati
The integrability of the one-dimensional (1D) fermion chain model is investigated in the framework of the Quantum Inverse Scattering Method (QISM). We introduce a new R-operator fo…
