Desde la Ciencia de la Mula Francis: omes y sus colegas han estudiado la transición de un “grafeno molecular” a una disposición periódica que se conoce como estructura de Kekulé; en esta transición los fermiones de Dirac sin masa adquieren masa. La teoría predice que esta transición debería ir acompañada de la aparición de un campo gauge; estos físicos han observado que los fermiones tras adquirir masa se comportan como si estuvieran en un campo magnético. La aparición y desaparición de un campo magnético “aparente” (que los autores llaman “campo pseudomagnético”) ...
