Staggered Anisotropy Parameter Modification of the Perk-Schultz Model
نویسنده
چکیده
The Perk-Schultz model (anisotropic t-J model) with staggered disposition of the anisotropy parameter along a chain is considered and the corresponding ladder type integrable model is constructed. This is a generalization to spin-1 case of the staggered XXZ spin-1/2 model considered earlier. The corresponding Hamiltonian is calculated and, since it contains next to nearest neighbor interaction terms, can be written in a zig-zag form. The Algebraic Bethe Ansatz technique is applied and the eigenstates, along with eigenvalues of the transfer matrix of the model are found.

We develop the technique of Thermodynamic Bethe Ansatz to investigate the ground state and the spectrum in the thermodynamic limit of the staggered XXZ models proposed recently as an example of integrable ladder model. This model appeared due to staggered inhomogeneity of the anisotropy parameter ∆ and the staggered shift of the spectral parameter. We give the structure of ground states and low...
متن کاملNonintersecting String Model and Graphical Approach: Equivalence with a Ports Model
Using a graphical method we establish the exact equivalence of the partition function of a q-state nonintersecting string (NIS) model on an arbitrary planar, even-valenced, lattice with that of a q2-state Potts model on a related lattice. The NIS model considered in this paper is one in which the vertex weights are expressible as sums of those of basic vertex types, and the resulting Ports mode...
متن کاملNonlinear Integral Equations for Thermodynamics of the U q ( ̂ sl ( r + 1 ) ) Perk - Schultz Model
We propose a system of nonlinear integral equations (NLIE) which describes the thermodynamics of the Uq( ̂ sl(r + 1)) Perk-Schultz model. These NLIE correspond to a trigonometric analogue of our previous result, and contain only r unknown functions. In particular, they reduce to Takahashi’s NLIE for the XXZ spin chain if r = 1. We also calculate the high temperature expansion of the free energy....
متن کاملMagnetic and orbital ordering in the spinel MnV2O4.
Neutron inelastic scattering and diffraction techniques have been used to study the MnV2O4 spinel system. Our measurements show the existence of two transitions to long-range ordered ferrimagnetic states, the first collinear and the second noncollinear. The lower temperature transition, characterized by development of antiferromagnetic components in the basal plane, is accompanied by a tetragon...
