Vortex density waves and negative absolute resistance in patterned superconductors
Rogério M. da Silva, Clécio C. de Souza Silva
We study theoretically dynamical phases of vortices in superconducting films with arrays of obstacles. By performing a series of molecular dynamics simulations and analytical calcu…
Tunable anisotropic nonlinearity in superconductors with asymmetric antidot array
A. Yu. Aladyshkin, J. Van de Vondel, C. C. de Souza Silva +1
The influence of the spatial asymmetry of the pinning potential on the spectral composition of the voltage, induced in perforated superconducting Al bridges by the injection of a s…
Vortex-Antivortex annihilation dynamics in a square mesoscopic superconducting cylinder
Edson Sardella, Paulo Noronha Lisboa Filho, Clécio C. de Souza Silva +2
The dynamics of the annihilation of a vortex-antivortex pair is investigated. The pair is activated magnetically during the run of a simulated hysteresis loop on a square mesoscopi…
Dynamics of driven vortex-antivortex matter in superconducting films with a magnetic dipole array
Cléssio L. S. Lima, Clécio C. de Souza Silva, .
We investigate theoretically vortex-antivortex (v-av) matter moving in thin superconducting films with a regular array of in-plane magnetic dipoles. Our model considers v-av pair c…
Dipole-induced vortex ratchets in superconducting films with arrays of micromagnets
C. C. de Souza Silva, A. V. Silhanek, J. Van de Vondel +4
We investigate the transport properties of superconducting films with periodic arrays of in-plane magnetized micromagnets. Two different magnetic textures are studied: a square arr…
