Spin accumulation is a crucial but imprecise concept in spintronics. In metal-based spintronics it is characterized in terms of semiclassical distribution functions. In semiconductors with a strong spin-orbit coupling the spin accumulation is interpreted as a superposition of coherent eigenstates. Both views can be reconciled by taking into account the electron-electron interaction: a sufficien...

The coupling of non-relativistic anyons (called exotic particles) to an electromagnetic field is considered. Anomalous coupling is introduced by adding a spin-orbit term to the Lagrangian. Alternatively, one has two Hamiltonian structures, obtained by either adding the anomalous term to the Hamiltonian, or by redefining the mass and the NC parameter. The model can also be derived from its relat...

In this paper we attempt to reconstruct one of the last projects of Volodya Geyler which remained unfinished. We study motion of a quantum particle in the plane to which a halfline lead is attached assuming that the particle has spin 1 2 and the plane component of the Hamiltonian contains a spin-orbit interaction of either Rashba or Dresselhaus type. We construct the class of admissible Hamilto...

We introduce ŝ.n̂ where n̂ = ~r/|~r| which along with the velocity forms a spin-orbit interaction of the order of v/c whereas the usual spin-orbit interaction is of the order of v/c. The effective fractional charges obtained from this interaction are in good agreement with the experimental data of quantum Hall effect. The energy of the system diverges as l → ∞ indicating that there is a phase tra...

We propose a method to improve spin-orbit potentials of the Skyrme interaction in N > Z nuclei. New spin-orbit parameters for Skyrme interactions SIII, SkM∗ and SGII are shown to yield better agreement with empirical spin-orbit splittings than the original ones, not only in 16O but also in 208Pb. The isotope shifts in Pb nuclei and excitation energies of collective Gamow-Teller states in 48Sc, ...

The coupling of the breathing and rotational modes of the skyrmionskyrmion system leads to a nucleon-nucleon spin-orbit interaction of short range, as well as to spin-orbit potentials for the transitionsNN → N(1440)N , NN → NN(1440) and NN → N(1440)N(1440). The longest range behaviour of these spin-orbit potentials is calculated in closed form. Preprint HU-TFT-96-57
