Is the purely biquadratic spin 1 chain always massive?
Giuseppe Albertini
It is shown that the sl(2)q-invariant open antiferromagnetic XXZ spin chain with a boundary field has a gapless sector in the thermodynamic limit when its length is odd. Owing to a…

A novel exponent in the Equilibrium Shape of Crystals
S. R. Dahmen, B. Wehefritz, G. Albertini
A new exponent characterizing the rounding of crystal facets is found by mapping a crystal surface onto the asymmetric six-vertex model (i.e. with external fields h and v) and usin…

Direction dependent free energy singularity of the asymmetric six-vertex model
Giuseppe Albertini
The transition from the ordered commensurate phase to the incommensurate gaussian phase of the antiferroelectric asymmetric six-vertex model is investigated by keeping the temperat…
