Anomalous Hall Effect in non-commutative mechanics

نویسنده

چکیده

The anomalous velocity term in the semiclassical model of a Bloch electron deviates the trajectory from the conventional one. When the Berry curvature (alias noncommutative parameter) is a monopole in momentum space, as found recently in some ferromagnetic crystals while observing the anomalous Hall effect, we get a transverse shift, similar to that in the optical Hall effect. cond-mat/0606472, to appear in Phys.

Exotic Galilean Symmetry and Non-commutative Mechanics in Mathematical & in Condensed Matter Physics *

The " exotic " particle model with non-commuting position coordinates , associated with the two-parameter central extension of the planar Galilei group, can be used to derive the ground states of the Fractional Quantum Hall Effect. The relation to other NC models is discussed. Anomalous coupling is presented. Similar equations arise for a semiclassical Bloch electron, used to explain the anoma-...

Exotic galilean symmetry in the non-commutative plane, and the Hall effect

Quantum Mechanics in the non-commutative plane is shown to admit the “exotic” symmetry of the doubly-centrally-extended Galilei group. When coupled to a planar magnetic field whose strength is the inverse of the non-commutative parameter, the system becomes singular, and “Faddeev-Jackiw” reduction yields the “Chern-Simons” mechanics of Dunne, Jackiw, and Trugenberger. The reduced system moves a...

Exotic Galilean Symmetry and Non-Commutative Mechanics

Some aspects of the “exotic” particle, associated with the two-parameter central extension of the planar Galilei group are reviewed. A fundamental property is that it has non-commuting position coordinates. Other and generalized non-commutative models are also discussed. Minimal as well as anomalous coupling to an external electromagnetic field is presented. Supersymmetric extension is also con...

Se p 20 06 Non - commutative mechanics in mathematical & in condensed matter physics ∗

Non-commutative structures were introduced, independently and around the same time, in mathematical and in condensed matter physics. Souriau's construction applied to the two-parameter central extension of the planar Galilei group lead to the " exotic " particle, which has non-commuting position coordinates. A Berry-phase argument applied to the Bloch electron yields in turn a semiclassical mod...
