Resumen
Resolviendo las ecuaciones de Ginzburg-Landau, analizamos el estado de vórtice en un cuadrado superconductor con centros de anclaje circulares en forma de una estructura de Dados, generados por una fuente de calor pulsada y en presencia de un campo magnético aplicado. Resolvimos numéricamente las ecuaciones Ginzburg-Landau para describir el efecto de la temperatura de los defectos sobre el estado Abrikosov de la muestra. El láser pulsado produce una variación de la temperatura en cada defecto. Se muestra que un estado anómalo vórtice-anti-vórtice (A-aV), aparece espontáneamente hacia campos magnéticos altos. Esto podría deberse a la ruptura de la simetría de la muestra por la inclusión de los defectos térmicos.
