Kramers-wannier duality from conformal defects.
We demonstrate that the fusion algebra of conformal defects of a two-dimensional conformal field theory contains information about the internal symmetries of the theory and allows one to read off generalizations of Kramers-Wannier duality. We illustrate the general mechanism in the examples of the Ising model and the three-state Potts model.
متن کاملKramers-Wannier Approximation for the 3D Ising Model
We investigate the Kramers-Wannier approximation for the three-dimensional (3D) Ising model. The variational state is represented by an effective 2D Ising model, which contains two variational parameters. We numerically calculate the variational partition function using the corner transfer matrix renormalization group (CTMRG) method, and find its maximum with respect to the variational paramete...
متن کاملGravitational Billiards, Dualities and Hidden Symmetries
The purpose of this article is to highlight the fascinating, but only very incompletely understood relation between Einstein’s theory and its generalizations on the one hand, and the theory of indefinite, and in particular hyperbolic, Kac Moody algebras on the other. The elucidation of this link could lead to yet another revolution in our understanding of Einstein’s theory and attempts to quant...
متن کاملDualities for Exceptional Gauge Groups and Quantum Global Symmetries
We discuss our attempts to generalize the known examples of dualities in N = 1 supersymmetric gauge theories to exceptional gauge groups. We derive some dual pairs from known examples connected to exceptional groups and find an interesting phenomenon: sometimes the full global symmetry is “hidden” on the magnetic side. It is not realized as a symmetry on the fundamental fields in the Lagrangian...
متن کاملSymmetries and Dualities in Name-Passing Process Calculi
We study symmetries and duality between input and output in the π-calculus. We show that in dualisable versions of π, including πI and fusions, duality breaks with the addition of ordinary input/output types. We illustrate two proposals of calculi that overcome these problems. One approach is based on a modification of fusion calculi in which the name equivalences produced by fusions are replac...
