Critical Q=1 Potts Model and Temperley-Lieb Stochastic Processes
Paul A. Pearce, Vladimir Rittenberg, Jan de Gier
We consider the groundstate wave function and spectra of the -site XXZ invariant quantum spin chain with . This chain is related to the critical Q=…

Spontaneous Breaking of Translational Invariance and Spatial Condensation in Stationary States on a Ring: II. The Charged System and the Two-component Burgers Equations
Peter F. Arndt, Vladimir Rittenberg
We further study the stochastic model discussed in Ref.[2] in which positive and negative particles diffuse in an asymmetric, CP invariant way on a ring. The positive particles hop…

The Pokrovski-Talapov Phase Transitions and Quantum Groups
Haye Hinrichsen, Vladimir Rittenberg
We show that the XY quantum chain in a magnetic field is invariant under a two parameter deformation of the superalgebra. One is led to an extension of the braid group an…
