A note on the thermodynamic Bethe ansatz approach for excited states

Marcio Jose Martins

Published Jan 21, 1992• 3 citations
Publisher

Abstract

The author proposes and analyses the thermodynamic Bethe ansatz equations for the first excited state in the minimal model M 5 perturbed by the subleading thermal field. Such states and the ground states have a different singular point in their scaling free energy.

New thermodynamic Bethe ansatz equations without strings

C. Destri, Hector J. de Vega

We present a computational framework not based on the string hypothesis for the thermodynamics of statistical and quantum field theory models solvable by the Bethe ansatz. In the cases of XXZ Heisenberg chain and the sine-Gordon quantum field theory we derive a single nonlinear integral equation which determines the free energy (or ground-state scaling function). Our approach is very effective at high temperature, and correctly reproduces the low-temperature central charge and the analytic structure of the corrections.

New Approach to Thermal Bethe Ansatz

C. Destri, Hector J. de Vega

We present a new approach to the calculation of thermodynamic functions for crossing-invariant models solvable by Bethe Ansatz. In the case of the XXZ Heisemberg chain we derive, for arbitrary values of the anysotropy, a {\bf single} non--linear integral equation from which the free energy can be exactly calculated. The high--temperature expansion follows in a sistematic and relatively simple way. For low temperatures we obtain the correct central charge and predict the analytic structure of the full expansion around $T=0$. Furthermore, we derive a single non-linear integral equation describing the finite--size ground--state energy of the Sine--Gordon quantum field theory. PACS: 05.30, 03.70. 75.10.5

An Extension of the Thermal Bethe Ansatz: One-Dimensional Hubbard Model

Tohru Koma

The thermodynamics of the one-dimensional Hubbard model is reduced to a system of algebraic equations through an extension of our thermal Bethe ansatz. This new formalism is free from the string conjecture, or more basically from the unproven assumption of the completeness of the Bethe states.

The critical boundary RSOS M(3,5) model

Omar El Deeb

We consider the critical nonunitary minimal model M (3, 5) with integrable boundaries and analyze the patterns of zeros of the eigenvalues of the transfer matrix and then determine the spectrum of the critical theory using the thermodynamic Bethe ansatz ( TBA ) equations. Solving the TBA functional equation satisfied by the transfer matrices of the associated A 4 restricted solid-on-solid Forrester–Baxter lattice model in regime III in the continuum scaling limit, we derive the integral TBA equations for all excitations in the ( r , s ) = (1, 1) sector and then determine their corresponding energies. We classify the excitations in terms of ( m , n ) systems .
