Two dimensional fermions in four dimensional YM

چکیده
Dirac fermions in the fundamental representation of SU(N) live on a two dimensional torus flatly embedded in R4. They interact with a four dimensional SU(N) Yang Mills vector potential preserving a global chiral symmetry at finite N . As the size of the torus in units of 1 ΛSU(N) is varied from small to large, the chiral symmetry gets spontaneously broken in the infinite N limit.

متن کاملBrane-Localized Goldstone Fermions in Bulk Supergravity
We construct the action and transformation laws for bulk five-dimensional AdS supergravity coupled to one or two brane-localized Goldstone fermions. The resulting bulk-plus-brane system gives a model-independent description of branelocalized supersymmetry breaking in the Randall-Sundrum scenario. We explicitly reduce the action and transformation laws to spontaneously broken four-dimensional su...
متن کاملAnomalies on Six Dimensional Orbifolds
We consider localized anomalies in six dimensional Zn orbifolds. We give a very simple expression for the contribution of a bulk fermion to the fixed point gauge anomaly that is independent of the order n of the orbifold twist. We show it can be split into three terms, two of which are canceled by bulk fermions and Green-Schwarz four forms respectively. The remaining anomaly carries an integer ...
متن کاملDelamination of Two-Dimensional Functionally Graded Multilayered Non-Linear Elastic Beam - an Analytical Approach
Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...
متن کاملSpatially Anisotropic Four-Dimensional Gauge Interactions, Planar Fermions and Magnetic Catalysis
We consider magnetic catalysis in a field-theoretic system of (3+1)-dimensional Dirac fermions with anisotropic kinetic term. By placing the system in a strong external magnetic field, we examine magnetically-induced fermion mass generation. When the coupling anisotropy is strong, in which case the fermions effectively localize on the plane, we find a significant enhancement of the induced mass...
