Geometrical dependence of information in 2d critical systems
Speaker(s): Paul Fendley
Abstract: In both classical and quantum critical systems, universal contributions to the mutual information and Renyi entropy depend on geometry. I will first explain how in 2d classical critical systems on a rectangle, the mutual information depends on the central charge in a fashion making its numerical ext... read more

Topological Order in Spin Systems
Speaker(s): Paul Fendley
Abstract: Much effort has been devoted to the study of systems with topological order, motivated by practical issues as well as more field theoretical and mathematical concerns. This talk will give an overview of some of the field, describing abelian systems relevant to the search for spin liquids, and no... read more

From few to many
Speaker(s): Paul Fendley
Abstract: I discuss a class of systems with a very special property: exact results for physical quantities can be found in the many-body limit in terms of the original (bare) parameters in the Hamiltonian. A classic result of this type is Onsager and Yang's formula for the magnetization in the Ising model. I ... read more
