The Wave Functions for the Free-Fermion Part of the Spectrum of the Quantum Spin Models
F. C. Alcaraz, Yu. G. Stroganov
We conjecture that the free-fermion part of the eigenspectrum observed recently for the Perk-Schultz spin chain Hamiltonian in a finite lattice with …
Free fermion branches in some quantum spin models
F. C. Alcaraz, Yu. G. Stroganov
Extensive numerical analysis of the eigenspectra of the invariant Perk-Schultz Hamiltonian shows some simple regularities for a significant part of the eigenspectrum. Ins…
A new way to deal with Izergin-Korepin determinant at root of unity
Yu. G. Stroganov
I consider the partition function of the inhomogeneous 6-vertex model defined on the by square lattice. This function depends on 2n spectral parameters and atta…
The Finite Size SU(3) Perk-Schultz Model with Deformation Parameter q=exp(i 2 pi/3)
F. C. Alcaraz, Y. Stroganov
From extensive numeric diagonalizations of the SU(3) Perk-Schultz Hamiltonian with a special value of the anisotropy and different boundary conditions, we have observed simple regu…
