The fractional quantum Hall effect(FQHE) arises from strong correlations between electrons when they are confined to two dimensions and exposed to a strong magnetic field. The underlying physics is the formation of topological particles called composite fermions(CFs), electron-vortex bound states whose integer quantum Hall effect explains a large majority of the observed FQHE states.

Subject field(s)
  • Atomic Physics
OBS

The basic physical principle underlying the Hall effect is the Lorentz force. When an electron moves along a direction perpendicular to an applied magnetic field, it experiences a force acting normal to both directions, and moves in response to this force and the force effected by the internal electric field.

Los alones aparecen directamente en el EHCF. Según la construcción cuyo esquema me he limitado a describir, en el EHCF los electrones son, en cierta manera, "superfermiones".
