Hall Effect Phenomena

Hall effect in an AC electric field and related phenomena

Nonlinear Hall effect in an AC electric field and related phenomena. Abstract It has been shown that in metals and semiconductors the joint action of permanent magnetic and AC electric fields leads to arising of DC surface electric current. The physical reason for such a current is due to essentially non-linear dynamics of electronic gas in the surface layer. In adiabatic limit the analytical e...

Conformal field theory description of mesoscopic phenomena in the fractional quantum Hall effect

We give a universal description of the mesoscopic effects occurring in fractional quantum Hall disks due to the Aharonov–Bohm flux threading the system. The analysis is based on the exact treatment of the flux within the conformal field theory framework and is relevant for all fractional quantum Hall states whose edge states CFTs are known. As an example we apply this scheme for the parafermion...

The Effect of Immigration on Criminal Phenomena

Migration as a human phenomenon has some consequences and repercussions. One of these effects is crime commitment and inducing disturbance in land and national security in immigrants' residence country, in other word, international migration, especially illegal migration, have different penal-security effects. Finding reason that the permeability of borders and increasing illegal traffic, drug ...

Theory of spin Hall magnetoresistance (SMR) and related phenomena.

We review the so-called spin Hall magnetoresistance (SMR) in bilayers of a magnetic insulator and a metal, in which spin currents are generated in the normal metal by the spin Hall effect. The associated angular momentum transfer to the ferromagnetic layer and thereby the electrical resistance is modulated by the angle between the applied current and the magnetization direction. The SMR provide...
