Perimeter Bethe ansatz

Journal of Physics A: Mathematical and General, 1987
The partition function of a finite Z-invariant six-vertex lattice model (with a prescribed arrow configuration at the boundary) is given. The expression is of the same type that occurs in the Bethe ansatz, but there are no 'wavenumber' equations to solve.

The Bethe ansatz

Journal of Physics A: Mathematical and Theoretical, 2016
We give a pedagogical introduction to the Bethe ansatz techniques in integrable QFTs and spin chains. We first discuss and motivate the general framework of asymptotic Bethe ansatz for the spectrum of integrable QFTs in large volume, based on the exact S-matrix. Then we illustrate this method in several concrete theories. The first case we study is the

Thermodynamic Bethe Ansatz

2020
Abstract The Thermodynamic Bethe Ansatz (TBA) allows us to study finite size and finite temperature effects of an integrable model. This chapter investigates the integral equations that determine the free energy and gives their physical interpretation.

Algebraic Bethe Ansatz

2017
The Algebraic Bethe Ansatz (ABA) approach is essentially a second quantization of the coordinate one we used so far. It uses the Yang-Baxter algebra of the transfer matrix to generate the wavefunctions by applying certain operators (which can be interpreted as quasi-particle creation operators) to a reference state (known as the pseudo-vacuum).

Thermodynamical Bethe Ansatz

2009
Abstract The thermodynamics of a quantum field theory in an infinite volume can be determined by its S-matrix. This idea, originally proposed by R. Dashen, S.K. Ma, and H.J. Berstein, has been widely used to study the thermal properties of the integrable field theories in (1 + 1) dimensions. The reason consists of the particularly simple

The Algebraic Bethe Ansatz

2015
The algebraic Bethe Ansatz method for quantum integrable models was proposed by the Leningrad Group [1, 2, 3, 4, 5, 6, 7] in the late 1970s, based on YBE. This method was then generalized to open boundary integrable systems by Sklyanin [8] in 1988, through developing an equation accounting for the integrable boundaries.
