چکیده
We consider the partition function of the boundary OSp(2S + 2|2S) coset sigma model on an annulus, based on the lattice regularization introduced in the companion paper. Using results for the action of OSp(2S+2|2S) and BL(2) on the corresponding spin chain, as well as mini-superspace and small g σ calculations, we conjecture the full spectrum and set of degeneracies on the entire critical line. Potential relationship with the OSp(2S + 2|2S) Gross-Neveu model is also discussed.

Bethe Ansatz for a Quantum Supercoset Sigma Model
We study an integrable conformal OSp(2m+2|2m) supercoset model as an analog to the AdS5 × S5 superstring world-sheet theory. Using the known S-matrix for this system, we obtain integral equations for states of large particle number in an SU(2) sector, which are exact in the sigma model coupling constant. As a check, we derive as a limit the general classical Bethe equation of Kazakov, Marshakov...
متن کاملThe arboreal gas and the supersphere sigma model
We discuss the relationship between the phase diagram of the Q = 0 state Potts model, the arboreal gas model, and the supersphere sigma model S = OSP (1/2)/OSP (0/2). We identify the Potts antiferromagnetic critical point with the critical point of the arboreal gas (at negative tree fugacity), and with a critical point of the sigma model. We show that the corresponding conformal theory on the s...
متن کاملAssociative-algebraic approach to logarithmic conformal field theories
We set up a strategy for studying large families of logarithmic conformal field theories by using the enlarged symmetries and non–semi-simple associative algebras appearing in their lattice regularizations (as discussed in a companion paper). Here we work out in detail two examples of theories derived as the continuum limit of XXZ spin-1/2 chains, which are related to spin chains with supersymm...
متن کاملA NOTE ON THE osp(1|2s) THERMODYNAMIC BETHE ANSATZ EQUATION
A Bethe ansatz equation associated with the Lie superalgebra osp(1|2s) is studied. A thermodynamic Bethe ansatz (TBA) equation is derived by the string hypothesis. The high temperature limit of the entropy density is expressed in terms of the solution of the osp(1|2s) version of the Q-system. In particular for fundamental representation case, we also derive a TBA equation from the osp(1|2s) ver...

We construct a new off-shell N=8, d=1 nonlinear supermultiplet (4,8,4) proceeding from the nonlinear realization of the N=8, d=1 superconformal group OSp(4⋆|4) in its supercoset OSp(4|4) SU(2)R⊗{D,K}⊗SO(4) . The irreducibility constraints for the superfields automatically follow from appropriate covariant conditions on the osp(4⋆|4)-valued Cartan superforms. We present the most general sigma-mo...
