As the field increases, the Landau level spacing increases (diamagnetism), the Landau degeneracy increases (eB/h). This is possible thanks to the edges : the energy of the edge states decreases (edge states are paramagnetic)  and the edge states become progressively bulk Landau states.

Graphene, coined the “miracle material”, owes many wonder to its

electrons that exhibit relativity in a flat land. Cold gaseous atoms

 held in an artificial crystal made with lasers can emulate closely

 this behavior. Most recently, an experimental group in Zurich,

 Switzerland, has realized an artificial graphene that can be stretched

 beyond the cohesion of a real-life graphene sheet. To wit, its

 relativistic behavior ceases, the electrons become massive, and a new

 type of insulator emerges. This scenario has been hypothesized by

 theorists in the past few years and is genuinely topological. In our

 paper, we provide an accurate theoretical framework in which to

 analyze the cold atoms experiment. From the crystal made of lasers to

 a theoretical model that captures the signature of such a transition,

 we show conclusively the observed key properties of stretching the

 graphene sheet to the extreme with cold atoms. Most remarkably, at the

 transition point, the system behaves as both relativistic and

 non-relativistic at the same time, a scenario which will open new

 research directions in the near future.
