Effect of dielectric response on the quantum capacitance of graphene in a strong magnetic field
Effect of dielectric response on the quantum capacitance of graphene in a strong magnetic field
The quantum capacitance of graphene can be negative when the graphene is placed in a strong magnetic field, which is a clear experimental signature of positional correlations between electrons. Here we show that the quantum capacitance of graphene is also strongly affected by its dielectric polarizability, which in a magnetic …
