Evaluating the Applicability of Bandwidth Allocation Models for EON Slot Allocation
Rafael F. Reale, Romildo M. S. Bezerra, Gilvan Duraes +3
Bandwidth Allocation Models (BAMs) configure and handle resource allocation (bandwidth, LSPs, fiber, slots) in networks in general (IP/MPLS/DS-TE, optical domain, other). In this p…
Oscillatory behavior of the domain wall dynamics in a curved cylindrical magnetic nanowire
R. Moreno, V. L. Carvalho-Santos, A. P. Espejo +3
Understanding the domain wall dynamics is an important issue in modern magnetism. Here we present results of domain wall displacement in curved cylindrical nanowires at a constant…
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…
Curvature-induced changes in the magnetic energy of vortices and skyrmions in paraboloidal nanoparticles
V. L. Carvalho-Santos, R. G. Elias, J. M. Fonseca +1
Curvature effects are important for a proper description of the properties of magnetic systems. In this paper the exchange and dipolar energy of vortices on a paraboloidal shell is…
Topological magnetic solitons on a paraboloidal shell
P. S. C. Vilas-Boas, R. G. Elias, D. Altbir +2
We study the influence of curvature on the exchange energy of skyrmions and vortices on a paraboloidal surface. It is shown that such structures appear as excitations of the Heisen…
Coupling between magnetic field and curvature in Heisenberg spins on surfaces with rotational symmetry
Vagson L. Carvalho-Santos, Rossen Dandoloff
We study the nonlinear -model in an external magnetic field applied on curved surfaces with rotational symmetry. The Euler-Lagrange equations derived from the Hamiltonian yield…
