Is quantum tunneling possible for one photon?

Does tunneling mean that in a certain area a real photon turns into a virtual one, and then turns into a real one again? Could this lead to observable (vacuum) effects? However, a photon (unlike...

Quantum Hall Effect can be observed,if magnetic energy is more than energy of electric interaction; but in opposite inequality is it possible?Really?

Quantum Hall Effect can be observed, if magnetic energy (Landau levels) is more than electric energy (that is, (mobility) x (magnetic field B) > 1 , see Klaus von Klitzing - Nobel Lecture, page...

Could electric voltage along to the two-dimensional sample be associated with a cutoff parameter in Coulomb's law for interaction of electrons?

In the semiclassical approximation, at an electron gas temperature T, the electrons can overcome the mutual repulsion energy Е_{Coulomb}=e^{2}/r getting closer to each other up to the minimal...
