Abstract

 


I will discuss some aspects of recent work on the Cauchy problem in laboratory coordinates for the sine-Gordon equation,  subject to a semiclassical scaling that introduces an essential  separation of scales into the dynamics.  This type of scaling  naturally occurs in the modeling of superconducting Josephson  tunneling junctions in which macroscopic (laboratory scale)  excitations create a large number of quanta of magnetic flux whose  nonlinear interactions can become complicated.  This is joint work  with Robert Buckingham.
