Free fermion representation of a boundary conformal field theory.
The theory of a massless two-dimensional scalar field with a periodic boundary interaction is considered. At a critical value of the period this system defines a conformal field theory and can be re-expressed in terms of free fermions, which provide a simple realization of a hidden SU(2) symmetry of the original theory. The partition function and the boundary S-matrix can be computed exactly as...
متن کاملSupersymmetric 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.
متن کاملFree Field Theory as a String Theory?
An approach to systematically implement open-closed string duality for free large N gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganisation of the Feynman diagrams contributing to free field correlators. We also indicate why the resulting integrand on moduli space has the right features to be that of a string theory on AdS.
متن کاملOverlap lattice fermion in a gravitational field
We construct a lattice Dirac operator of the overlap-type which describes the propagation of the Dirac fermion in an external gravitational field. The local Lorentz symmetry is manifestly realized as a lattice gauge symmetry, while the general coordinate invariance is expected to be restored only in the continuum limit. Our doubler-free Dirac operator obeys the conventional Ginsparg-Wilson rela...
متن کاملCluster-Based Image Segmentation Using Fuzzy Markov Random Field
Image segmentation is an important task in image processing and computer vision which attract many researchers attention. There are a couple of information sets pixels in an image: statistical and structural information which refer to the feature value of pixel data and local correlation of pixel data, respectively. Markov random field (MRF) is a tool for modeling statistical and structural inf...
