An international team of researchers has developed an artificial semiconductor structure that has superimposed a pattern created by advanced fabrication methods that are precise at the nanometer scale. The pattern is similar to the honeycomb lattice that occurs in graphene. The device, called "artificial graphene" (AG), simulates quantum behavior of strongly interacting electrons. The research team sees the AG-device as a first step towards the realization of an innovative class of solid-state quantum simulators to explore fundamental quantum physics.
