Quantum simulator prototype replicates structure of graphene
Quantum simulator prototype replicates structure of graphene: The simulator developed by the researchers consists of a honeycomb lattice realized on the surface of a Gallium Arsenide (GaAs) heterostructure using advanced nanofabrication methods. The artificial honeycomb lattice structure replicates that of graphene, a material in which electrons behave in a peculiar way because of the crystal-lattice geometry. With the ability to modify key parameters such as the lattice constant of the artificial lattice, the researchers are in the position to explore different regimes of electron-electron interactions in graphene-like systems.
