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…

On geometry-dependent vortex stability and topological spin excitations on curved surfaces with cylindrical symmetry

Vagson L. Carvalho-Santos, Felipe A. Apolonio, Nemésio M. Oliveira-Neto

We study the Heisenberg Model on cylindrically symmetric curved surfaces. Two kinds of excitations are considered. The first is given by the isotropic regime, yielding the sine-Gor…
