" Boundary field theory approach to Josephson devices "



Abstract

I show that some superconducting Josephson devices may be regarded as a 
condensed matter realization of a two boundary sine Gordon model.  
Using boundary field theory methods I will compute both the DC 
Josephson current and the normal component of the current-response of 
SQUIDs to an externally applied voltage.  The approach helps in 
establishing new and somewhat unexpected connections between 
superconducting devices and quantum impurity problems.
