Lyapunov exponent in the Vicsek model
L. H. Miranda-Filho, T. A. Sobral, A. J. F. de Souza +2
The well-known Vicsek model describes the dynamics of a flock of self-propelled particles (SPPs). Surprisingly, there is no direct measure of the chaotic behavior of such systems.…
Paramagnetic excited vortex states in superconductors
Rodolpho Ribeiro Gomes, Mauro M. Doria, Antonio R. de C. Romaguera
We consider excited vortex states, which are vortex states left inside a superconductor once the external applied magnetic field is switched off and whose energy is lower than of t…
Evidence for skyrmions in the high-temperature superconductors
Alfredo A. Vargas-Paredes, Marco Cariglia, Mauro M. Doria +2
We claim that the charge density wave recently found by resonant soft x-ray scattering in layered copper oxides is the tetragonal symmetry defined by the distance between neighbor…
The ground states of the two-component order parameter superconductor
Mauro M. Doria, Antonio R. de C. Romaguera, F. M. Peeters
We show that in presence of an applied external field the two-component order parameter superconductor falls in two categories of ground states, namely, in the traditional Abrikoso…
Vortex patterns in a superconducting-ferromagnetic rod
Antonio R. de C. Romaguera, Mauro M. Doria, F. M. Peeters
A superconducting rod with a magnetic moment on top develops vortices obtained here through 3D calculations of the Ginzburg-Landau theory. The inhomogeneity of the applied field br…
Three-dimensional Ginzburg-Landau simulation of a vortex line displaced by a zigzag of pinning spheres
Mauro M. Doria, Antonio R. de C. Romaguera, Welles A. M. Morgado
A vortex line is shaped by a zigzag of pinning centers and we study here how far the stretched vortex line is able to follow this path. The pinning center is described by an insula…
