Graphene wormhole trapped by external magnetic field

Graphene wormhole trapped by external magnetic field

In this work we study the behavior of massless fermions in a graphene wormhole and in the presence of an external magnetic field. The graphene wormhole is made from two sheets of graphene which play the roles of asymptotically flat spaces connected through a carbon nanotube with a zig-zag boundary....
