| Abstract: | Graphene has attracted enormous attention over the past years in condensed matter physics.The most interesting feature of graphene is that its low-energy excitations are relativistic Dirac fermions.Such feature is the origin of many topological properties in graphene-like physics.On the other hand,ultracold quantum gas trapped in an optical lattice has become a unique setting for quantum simulation of condensed matter physics.Here,we mainly review our recent work on quantum simulation of graphene-like physics with ultracold atoms trapped in a honeycomb or square optical lattice,including the simulation of Dirac fermions and quantum Hall effect with and without Landau levels.We also present the related experimental advances. |
