$U_q[OSp(3|2)]$ quantum chains with quantum group invariant boundaries

Abstract

Based on the finite-size analysis of the spectrum of the quantum group invariant deformation of the $OSp(3|2)$ superspin chain we identify the operator content of the conformal field theory describing the model in its scaling limit. We find that the macroscopic degeneracy of the conformal weights observed in the thermodynamic limit of the isotropic superspin chain is lifted by the deformation.
