 201\, 2ème étage\, Bât 100\, Campus d'Orsay - 3 Juin 13 11:00
DESCRIPTION:Effect of winding edge currents\nAndrey Yanovsky (B. Verkin Ins
 titute for Low Temperature Physics and Engineering of the NAS of Ukraine)\
 nSome degrees of freedom “interact”' with the velocity winding of traj
 ectories\, e.g. spin.  We discuss the connection between spintronics and 
 winding: namely its relation to Spin-hall effect and Thomas precession. Fu
 rther we discuss persistent currents for particles with internal degrees o
 f freedom. The currents arise because of winding properties essential for 
 the chaotic motion of the particles in a confined geometry. The currents d
 o not change the particle concentrations or thermodynamics\, similar to th
 e skipping orbits in a magnetic field. One of the possible realization are
  persistent currents in conditions of “extrinsic”' spin Hall effect. T
 he effect is classical in contrast to similar currents predicted for condi
 tions of quantum “intrinsic” spin Hall effect. An analytical solution 
 has been found in an Ornstein-Uhlenbeck process. Weak dependence of the wi
 nding currents on the form of confined potential has been uncovered. The r
 esults can be of interest beyond the scope of phenomena associated with th
 e spin Hall effect.\nS. Ouvry\, L .Pastur\, A. Yanovsky\, Physics Letters
