1. 1. Transport effects in hybrid circuit QED structures

   Författare :Christian Bergenfeldt; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Bergenfeldt;

   Sammanfattning : This dissertation deals with the electron-photon interplay in hybrid circuit QED structures. The aim is to provide a framework in which this interplay can be understood and to predict experimentally measurable transport effects. In addition an application of this interplay is proposed.
