Skyrmions are quasi-particles that were originally proposed theoretically by the British physicist Tony Skyrme. Magnetic skyrmions correspond to a distribution of spins pointing in all directions under a sphere, and are present in ferromagnetic materials, liquid crystals, Bose-Einstein condensates and others. Recently, magnetic skyrmions were observed in chiral magnets. In these materials…
In this work, we will study the dynamic behavior of skyrmions on chiral magnets, in the presence of periodic pinning potentials. In particular, we will analyze pinning centers with funnel-type geometry. Initially proposed by the English physicist Tony Skyrme, skyrmions are quasi-particles that correspond to a distribution of spins pointing in all directions under a sphere and are present …
In the present work we propose the study of critical currents and dynamical behavior of vortices in type II Superconducting stripes with Kagomé and hexagonal arrays of pinning centers. In addition to the finite geometry and pinning effects, the system behavior when external parameters such as temperature and magnetic field are changed will be analyzed. When the transport current J exceeds…
One of the most used mechanisms to increase the critical current in type II high critical temperature superconducting materials is the pinning of vortices. When a transport current J is applied and exceed a critical value Jc, the vortices move and dissipate energy. Several efforts have been made from the experimental point of view to increase the effect of pinning in this type of material…

Magnetic skyrmions corresponds to a spin distribution pointing in all directions around a sphere, and they are present in ferromagnetic materials, liquid crystals, Bose-Einstein condensates and others. Recently, magnetic skyrmions were also observed in chiral magnets. In these materials, skyrmions form a vortex-like structure and organize themselves in a regular triangular lattice due to …
