"Quantized Faraday effect: a QED approach. Applications to Graphene-like system"
Dra. Aurora Perez Martínez, ICIMAF, La Habana
Faraday rotation in the quantum relativistic limit is studied. Starting from
the photon self-energy in the presence
of a constant magnetic field the rotation of the polarization vector of a
plane electromagnetic wave which travel
along the fermion-antifermion gas is studied. The connection between Faraday
effect and quantum Hall effect
(QHE) is discussed. The Faraday effect is also investigated for a massless
relativistic (2+1)-dimensional fermion
system (Graphene-like system) which is derived by using the compactification
along the dimension parallel to the magnetic field. The
Faraday angle shows a quantized behavior as Hall conductivity in two and
three dimensions.
