Magnus force on skyrmions in ferromagnets and quantum Hall systems.
The topological solitons, or " skyrmions " , in a planar ferromagnet experience a Magnus force proportional to the product of their velocity and the surrounding magnetization. It has been suggested that the charged quasiparticles near filling factor ν = 1 in the GaAs quantum Hall effect are skyrmions. If so, we might expect this spin-induced Magnus force to act on the quasiparticles in addition...

متن کاملThe Quantum Hall effect, Skyrmions and Anomalies
We discuss the properties of Skyrmions in the Fractional Quantum Hall effect (FQHE). We begin with a brief description of the Chern-Simons-Landau-Ginzburg description of the FQHE, which provides the framework in which to understand a new derivation of the properties of FQHE Skyrmions (S. Baez, A.P. Balachandran, A. Stern and A. Travesset cond-mat 9712151) from anomaly and edge considerations. I...
متن کاملField Theory of Quantum Hall Effects, Composite Bosons, Vortices and Skyrmions
A field theory of quantum Hall effects is constructed based on the composite-boson picture. It is tightly related with the microscopic wave-function theory. The characteristic feature is that the field operator describes solely the physical degrees of freedom representing the deviation from the Laughlin state. It presents a powerful tool to analyze excited states within the lowest Landau level....
متن کاملSkyrmions in the Fractional Quantum Hall Effect
It is verified that, at small Zeeman energies, the charged excitations in the vicinity of 1/3 filled Landau level are skyrmions of composite fermions, analogous to the skyrmions of electrons near filling factor unity. These are found to be relevant, however, only at very low magnetic fields. PACS numbers: 73.40.Hm Typeset using REVTEX 0Accepted for publication in Solid State Communications (199...
