On the normalization of the partition function of Bethe Ansatz systems
F. Woynarovich
In this note I revisit the calculation of partition function of simple one dimensional systems solvable by Bethe Ansatz. Particularly I show that by the precise definition and trea…
O(1) contribution of saddle point fluctuations to the free energy of Bethe Ansatz systems
F. Woynarovich
We develop a method to calculate the contribution of the saddle-point fluctuations to the partition function of systems soluble by the Bethe Ansatz. Using this method we give the O…
On the symmetry of excitations in SU(2) Bethe Ansatz systems
F. Woynarovich
Using the XXX Heisenberg chain as an example, based on the symmetry properties of the eigenstates with respect to reversing all the spins we argue, that the basic SU(2) symmetry of…
Scaling limit of the one-dimensional attractive Hubbard model: The non-half-filled band case
F. Woynarovich, P. Forgacs
The scaling limit of the less than half filled attractive Hubbard chain is studied. This is a continuum limit in which the particle number per lattice site, n, is kept finite (0<n<…
Scaling limit of the one-dimensional attractive Hubbard model: The half-filled band case
F. Woynarovich, P. Forgacs
The scaling limit of the higher level Bethe Ansatz (HLBA) equations for a macroscopically half-filled Hubbard chain is considered. These equations practically decouple into three d…
