Thermodynamic Bethe Ansatz for the Spin-1/2 Staggered XXZ- Model
V. V. Mkhitaryan, A. G. Sedrakyan
We develop the technique of Thermodynamic Bethe Ansatz to investigate the ground state and the spectrum in the thermodynamic limit of the staggered models proposed recently a…
Integrable Chain Model with Additional Staggered Model Parameter
D. Arnaudon, R. Poghossian, A. Sedrakyan +1
The generalization of the Yang-Baxter equations (YBE) in the presence of Z_2 grading along both chain and time directions is presented. The XXZ model with staggered disposition alo…
The measure in three dimensional Nambu-Goto string theory
J. Ambjorn, A. Sedrakyan
We show that the measure of the three dimensional Nambu-Goto string theory has a simple decomposition as a measure on two parameter group of induced area-preserving transformations…
The 3d Ising Model represented as Random Surfaces
J. Ambjorn, A Sedrakyan, G. Thorleifsson
We consider a random surface representation of the three-dimensional Ising model.The model exhibit scaling behaviour and a new critical index $\k$ which relates $\g_{string}$ for t…
