Boundary S matrices with N = 2 supersymmetry

چکیده
We propose the exact boundary S matrix for breathers of theN = 2 supersymmetric sine-Gordon model. We argue that this S matrix has three independent parameters, in agreement with a recently-proposed action. We also show, contrary to a previous claim, that the “universal” supersymmetric boundary S matrix commutes with two supersymmetry charges. General N = 2 supersymmetric boundary integrable models are expected to have boundary S matrices with a similar structure.

Quantum integrable models that possess N = 2 supersymmetry are investigated on the half-space. Conformal perturbation theory is used to identify some N = 2 supersymmetric boundary integrable models, and the effective boundary Landau-Ginzburg formulations are constructed. It is found that N = 2 supersymmetry largely determines the boundary action in terms of the bulk, and in particular, the boun...

متن کاملTricritical Ising Model with a Boundary ∗
We study the integrable and supersymmetric massivê φ (1,3) deformation of the tricritical Ising model in the presence of a boundary. We use constraints from su-persymmetry in order to compute the exact boundary S-matrices, which turn out to depend explicitly on the topological charge of the supersymmetry algebra. We also solve the general boundary Yang-Baxter equation and show that in appropria...
متن کاملExact solution of the supersymmetric sinh-Gordon model with boundary
The boundary supersymmetric sinh-Gordon model is an integrable quantum field theory in 1+1 dimensions with bulk N = 1 supersymmetry, whose bulk and boundary S matrices are not diagonal. We present an exact solution of this model. In particular, we derive an exact inversion identity and the corresponding thermodynamic Bethe Ansatz equations. We also compute the boundary entropy, and find a rich ...
متن کاملSupersymmetry breaking in 5 - dimensional space - time with S 1 / Z 2 compactification
We consider supersymmetric models in 5-dimensional space-time compactified on S/Z2 orbifold where N = 2 supersymmetry is explicitly broken down to N = 1 by the orbifold projection. We find that the residual N = 1 supersymmetry is broken spontaneously by a stable classical wall-like field configurations which can appear even in the simple models discussed. We also consider some simple models of ...
