The superconductive field effect
We investigate the suppression of superconductivity by strong electric fields in thin films and related structures. A central idea is the analogy between superconducting quasiparticles and relativistic quantum fields, including a superconducting counterpart of Schwinger pair production.
Research questions
What we are trying to understand
How can static electric fields modify superconductivity despite conventional screening arguments?
Which microscopic mechanisms reproduce experimentally observed field effects?
Can electrically controlled superconductivity be turned into useful device architectures?
