Quasi-particle swap between graphene layers

(Springer) Belgian scientists have used a particle physics theory to describe the behavior of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In a paper published in EPJ B, researchers, studied the behavior of excitons in a bilayer of graphene through an analogy with excitons evolving in two abstract parallel worlds, described with equations typically used in high-energy particle physics.
