New conjecture for the Perk-Schultz models
F. C. Alcaraz, Yu. G. Stroganov
We present a new conjecture for the Perk-Schultz models. This conjecture extends a conjecture presented in our article (Alcaraz FC and Stroganov YuG (2002) J. Phys. A vol…

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 …

O(1) loop model with different boundary conditions and symmetry classes of alternating-sign matrices
A. V. Razumov, Yu. G. Stroganov
This work as an extension of our recent paper where we have found a numerical evidence for the fact that the numbers of the states of the fully packed loop (FPL) model with fixed l…
