We first obtain an expression of the quantum capacitance of a two layer system. In addition, we calculate the many-body exchange-correlation energy and quantum capacitance of the hybrid double layer graphene system at zero-temperature. We show an enhancement of the majority density layer thermodynamic density-of-states owing to an increasing interlayer interaction between two layers near the Dirac point.
