The boundary supersymmetric sine-Gordon model revisited

We argue that, contrary to previous claims, the supersymmetric sine-Gordon model with boundary has a two-parameter family of boundary interactions which preserves both integrability and supersymmetry. We also propose the corresponding boundary S matrix for the first supermultiplet of breathers.

The boundary N = 2 supersymmetric sine-Gordon model

We construct an action for the N = 2 supersymmetric sine-Gordon model on the half-line, which we argue is both supersymmetric and integrable. The boundary interaction depends on three continuous boundary parameters, as well as the bulk mass parameter.

Boundary Sine-Gordon Interactions at the Free Fermion Point

We study bosonization of the sine-Gordon theory in the presence of boundary interactions at the free fermion point. In this way we obtain the boundary S-matrix as a function of physical parameters in the boundary sine-Gordon Lagrangian. The boundary S-matrix can be matched onto the solution of Ghoshal and Zamolodchikov, thereby relating the formal parameters in the latter solution to the physic...

Fractional-Spin Integrals of Motion for the Boundary Sine-Gordon Model at the Free Fermion Point

We construct integrals of motion (IM) for the sine-Gordon model with boundary at the free Fermion point (β2 = 4π) which correctly determine the boundary S matrix. The algebra of these IM (“boundary quantum group” at q = 1) is a one-parameter family of infinite-dimensional subalgebras of twisted ŝl(2). We also propose the structure of the fractional-spin IM away from the free Fermion point (β2 6...

Supersymmetric Integrable Field Theories and Eight Vertex Free Fermion Models

We relate n = 1 supersymmetric integrable eld theories such as the supersym-metric sinh-Gordon and perturbed SUSY Yang-Lee models to the Eight Vertex Free Fermion models deened on the lattice. This association makes it possible to obtain correct UV central charges using thermodynamic Bethe ansatz.
