Josephson and Quantum Hall Effects vs Quantum Electrodynamics
Alexander Penin (University of Alberta, Edmonton)
Seminar Room 3, 15:00
Vacuum polarization results in a weak dependence of the
Josephson and von Klitzing constants on the magnetic field
strength. This remarkable manifestation of a fine nonlinear
quantum field effect in collective phenomena in condensed
matter can be observed in a dedicated experiment.
