Spin wave vortex from the scattering on Bloch point solitons
Vagson L. Carvalho-Santos, Ricardo Gabriel Elías, Alvaro S. Núñez
The interaction of a spin wave with a stationary Bloch point is studied. The topological non-trivial structure of the Bloch point manifests in the propagation of spin waves endowin…
Spin waves scattering on a Bloch point
R. G. Elías, V. L. Carvalho-Santos, A. S. Núñez +1
We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an elect…
Thermally Assisted Current-Driven Skyrmion Motion
Roberto E. Troncoso, Alvaro S. Núñez
We study the behavior of skyrmions in thin films under the action of stochastic torques arising from thermal fluctuations. We find that the Brownian motion of skyrmions is describe…
Trigonal distortion of topologically confined channels in bilayer Graphene
A. S. Núñez, E. Suárez Morell, P. Vargas
In this work we show that the trigonal warping of the electronic bands in bilayer graphene dramatically modifies the behavior of the one-dimensional modes topologically confined du…
Spin Transfer Without Spin Conservation
Alvaro S. Núñez, A. H. MacDonald
We propose a general theory of the spin-transfer effects that occur when current flows through inhomogeneous magnetic systems. Our theory does not rest on an appeal to conservation…
Optical spin transfer in ferromagnetic semiconductors
J. Fernández-Rossier, Alvaro S. Núñez, M. Abolfath +1
Circularly polarized laser pulses that excite electron-hole pairs across the band gap of (III,Mn)V ferromagnetic semiconductors can be used to manipulate and to study collective ma…
