Spin Hall magnetoresistance at Pt/CoFe2O4 interfaces and texture effects
(American Institute of Physics, 2014-10)
We report magnetoresistance measurements on thin Pt bars grown on epitaxial (001) and (111) CoFe2O4 (CFO) ferrimagnetic insulating films. The results can be described in terms of the recently discovered spin Hall ...
Nonmonotonic spin relaxation and decoherence in graphene quantum dots with spin-orbit interactions
(American Physical Society - APSCollege Park, 2014-03)
We investigate the spin relaxation and decoherence in a single-electron graphene quantum dot with Rashba and intrinsic spin-orbit interactions.We derive an effective spin-phonon Hamiltonian via the Schrieffer-Wolff ...
More on dual actions for massive spin-2 particles
(Iop Publishing Ltd, 2020-07-23)
Here we start from a dual version of Vasiliev's first order action for massless spin-2 particles (linearized first order Einstein-Hilbert) and derive, via Kaluza-Klein dimensional reduction fromD+ 1 toDdimensions, a set ...
Spin-glass behaviour on random lattices
(IOP PUBLISHING LTDBRISTOL, 2012-10)
The ground-state phase diagram of an Ising spin-glass model on a random graph with an arbitrary fraction w of ferromagnetic interactions is analysed in the presence of an external field. Using the replica method, and ...
Confinement of spin-0 and spin-1/2 particles in a mixed vector-scalar coupling with unequal shapes for the potentials
(Royal Swedish Acad Sciences, 2007-02-01)
The Klein - Gordon and the Dirac equations with vector and scalar potentials are investigated under a more general condition, V-v = V-s + constant. These isospectral problems are solved in the case of squared trigonometric ...

Noncommutativity due to spin
(AMER PHYSICAL SOC, 2010)
Using the Berezin-Marinov pseudoclassical formulation of the spin particle we propose a classical model of spin noncommutativity. In the nonrelativistic case, the Poisson brackets between the coordinates are proportional ...
Superadiabatic spin-preserving control of a single-spin qubit in a double quantum dot with spin–orbit interaction
(IOP Publishing, 2019-10)
A protocol for controlling the localization of an electron with a fixed projection of spin between two quantum dots in a material with spin-orbit (SO) interaction is studied. Due to SO coupling, the manipulation of the ...
