Calabi's diastasis as interface entropy

High Energy Physics - Theory 2014-08-06 v2 Algebraic Geometry

Abstract

We show that the entropy of certain conformal interfaces between N=(2,2)N=(2,2) sigma models that belong to the same moduli space, has a natural geometric interpretation in the large volume limit as Calabi's diastasis function. This is an extension of the well-known relation between the quantum K\"ahler potential and the overlap of canonical Ramond-Ramond ground states in N=(2,2)N=(2,2) models.
