Estados ligados en el Grafeno en presencia de campo magnético
Resumen
En este trabajo se estudian soluciones exactas para los estados ligados para un electrón de Dirac en Grafeno en presencia de varios campos magnéticos externos con simetría traslacional. Usando el Método de Iteración Asintótica, se resuelve la ecuación de Dirac-Weyl independiente del tiempo. Finalmente, se estudian los comportamientos del espectro discreto.
