Quench Disorder and Scalar Field Theory in the Presence of Boundary
Abstract
Disordered systems are interesting for many physical reasons. In this article, we study the renormalization group property of quenched disorder systems in the presence of a boundary. We construct examples of scalar field theories in various dimensions with both classical and quantum disorder localized at the boundary. We study these theories in -expansion and discuss properties of fixed points of the renormalization group flow.
