The Erwin Schrr Odinger International Institute for Mathematical Physics Field Theory on a Supersymmetric Lattice Field Theory on a Supersymmetric Lattice 1
A lattice-type regularization of the supersymmetric eld theories on a supersphere is constructed by approximating the ring of scalar superrelds by an integer-valued sequence of nite dimensional rings of supermatrices and using the diierencial calculus of non-commutative geometry. The regulated theory involves only nite number of degrees of freedom and is manifestly supersymmetric.
متن کاملThe Global Renormalization Group Trajectory in a Critical Supersymmetric Field Theory on the Lattice Z
We consider an Euclidean supersymmetric field theory in Z given by a supersymmetric Φ perturbation of an underlying massless Gaussian measure on scalar bosonic and Grassmann fields with covariance the Green’s function of a (stable) Lévy random walk in Z. The Green’s function depends on the Lévy-Khintchine parameter α = 3+ε 2 with 0 < α < 2. For α = 3 2 the Φ 4 interaction is marginal. We prove ...
متن کاملSupersymmetric Rings in Field Theory
We study the dynamics of BPS string-like objects obtained by lifting monopole and dyon solutions of N = 2 Super-Yang-Mills theory to five dimensions. We present exact traveling wave solutions which preserve half of the supersymmetries. Upon compactification this leads to macroscopic BPS rings in four dimensions in field theory. Due to the fact that the strings effectively move in six dimensions...
متن کاملParafermionic conformal field theory on the lattice
Finding the precise correspondence between lattice operators and the continuum fields that describe their long-distance properties is a largely open problem for strongly interacting critical points. Here we solve this problem essentially completely in the case of the three-state Potts model, which exhibits a phase transition described by a strongly interacting ‘parafermion’ conformal field theo...
متن کاملuse LATTICE FIELD THEORY
This review concentrates on progress in lattice QCD during the last two years and, particularly, its impact on phenomenology. The two main technical developments have been successful implementations of lattice actions with exact chiral symmetry, and results from simulations with two light dynamical flavours which provide quantitative estimates of quenching effects for some quantities. Results a...
