Harnessing the superconducting diode effect through inhomogeneous magnetic fields
Leonardo Rodrigues Cadorim, Edson Sardella, Clécio Clemente de Souza Silva
We propose a superconducting diode device comprising a central superconducting film flanked by two wires carrying an applied DC bias, suitably chosen so as to generate different as…
Polar order, shear banding, and clustering in confined active matter
Daniel Canavello, Rubens H. Damascena, Leonardo R. E. Cabral +1
We investigate the collective behavior of sterically interacting self-propelled particles confined in a harmonic potential. Our theoretical and numerical study unveils the emergenc…
Towards Magnonic Logic and Neuromorphic Computing: Controlling Spin-Waves by Spin-Polarized Current
Raí M. Menezes, Jeroen Mulkers, Clécio C. de Souza Silva +2
Spin-waves (magnons) are among the prime candidates for building fast yet energy-efficient platforms for information transport and computing. We here demonstrate theoretically and…
Tailoring High-Frequency Magnonics in Monolayer Chromium Trihalides
Raí M. Menezes, Denis Šabani, Cihan Bacaksiz +2
Monolayer chromium trihalides, the archetypal two dimensional (2D) magnetic materials, are readily suggested as a promising platform for high frequency magnonics. Here we detail th…
Mesoscale phase separation of skyrmion-vortex matter in chiral magnet-superconductor heterostructures
José F. Neto, Clécio C. de Souza Silva
We investigate theoretically the equilibrium configurations of many magnetic skyrmions interacting with many superconducting vortices in a superconductor-chiral magnet bilayer. We…
Stick-slip Phenomena and Memory Effects in Moving Vortex Matter
Lise Serrier-Garcia, Clécio C. de Souza Silva, Matias Timmermans +2
Manipulating vortices in non-conventional superconductors is nowadays a challenging path toward controlling functionalities for superconducting nanodevices. Here, we directly obser…
Conformal Vortex Crystals
Raí M. Menezes, Clécio C. de Souza Silva
We investigate theoretically globally nonuniform configurations of quantized-flux vortices in clean superconductors trapped by an external force field that induces a nonuniform vor…
A closer look at the low frequency dynamics of vortex matter
B. Raes, C. de Souza Silva, A. V. Silhanek +3
Using scanning susceptibility microscopy, we shed new light on the dynamics of individual superconducting vortices and examine the hypotheses of the phenomenological models traditi…
Local mapping of dissipative vortex motion
B. Raes, J. Van de Vondel, A. V. Silhanek +4
We explore, with unprecedented single vortex resolution, the dissipation and motion of vortices in a superconducting ribbon under the influence of an external alternating magnetic…
Stability of fractional vortex states in a two-band mesoscopic superconductor
Juan C. Pina, Clecio C. de Souza Silva, Milorad V. Milosevic
We investigate the stability of noncomposite fractional vortex states in a mesoscopic two-band superconductor within the two-component Ginzburg-Landau model. Our analysis explicitl…
A simple model for dynamical melting of moving vortex lattices interacting with periodic pinning
Clécio C. de Souza Silva, Gilson Carneiro
Melting of moving vortex lattices in clean superconducting films with periodic pinning is studied by a dynamical "cage" model, based on a mean-field treatment of Langevin's equatio…
Vortices in superconducting strips: interplay between surface effects and the pinning landscape
Clécio C. de Souza Silva, Leonardo R. E. Cabral, J. Albino Aguiar
Vortices in a narrow superconducting strip with a square array of pinning sites are studied. The interactions of vortices with other vortices and with external sources (applied mag…
