Strong-weak coupling duality in anisotropic current interactions
نویسندگان
چکیده
The recently proposed all orders βeta function is further investigated. By using a strong-weak coupling duality of the βeta function, and some added topology of the space of couplings we are able to extend the flows to arbitrarily large or small scales. Using a non-trivial RG invariant we are able to identify sine-Gordon, sinh-Gordon and Kosterlitz-Thouless phases. We also find an additional phase with cyclic or roaming RG trajectories.

Monopole-Particle Duality at Strong Electric Coupling
We consider the gauge interactions between non-Abelian magnetic monopoles at strong electric coupling. By drawing an analogy between the gauge freedom of an electric particle at weak electric coupling and that of a monopole at strong electric coupling we motivate that these monopoles interact under a magnetic copy of the residual symmetry group. This differs from the interactions of monopoles a...
متن کاملDuality and ‘particle’ democracy
Among the significant philosophical issues raised by the central role of physical dualities in recent fundamental research, one has a specific ontological flavor, as it concerns ‘dual entities’, i.e. entities exchanged by a duality mapping between theories. In particular, the type of duality that is known as weak/strong duality, or S-duality according to current terminology, seems to imply new ...
متن کاملNon-Abelian Strong-Weak Coupling Duality in (String-Derived) N=4 Supersymmetric Yang-Mills Theories
We study strong-weak coupling duality (S-duality) in N=4 supersymmetric nonAbelian Yang-Mills theories. These theories arise naturally as the low-energy limit of four-dimensional toroidal compactifications of the heterotic string. Firstly, we define the free energy in the presence of electric and magnetic fluxes using ’t Hooft’s prescription, i.e. through functional integrals at finite volume i...
متن کاملScattering Theory and Correlation Functions in Statistical Models with a Line of Defect
The scattering theory of the integrable statistical models can be generalized to the case of systems with extended lines of defect. This is done by adding the reflection and transmission amplitudes for the interactions with the line of inhomegeneity to the scattering amplitudes in the bulk. The factorization condition for the new amplitudes gives rise to a set of Reflection-Transmission equatio...
متن کاملStrong-Weak Coupling Duality in Four Dimensional String Theory
We present several pieces of evidence for strong-weak coupling duality symmetry in the heterotic string theory, compactified on a six dimensional torus. These include symmetry of the 1) low energy effective action, 2) allowed spectrum of electric and magnetic charges in the theory, 3) allowed mass spectrum of particles saturating the Bogomol’nyi bound, and 4) Yukawa couplings between massless n...
