Bilayer graphene is a recently isolated and intriguing class of many-body system with massive
chiral quasiparticles. We present theoretical results for the electronic compressibility of bilayer
graphene that are based on a four-band continuum band structure model combined with a ran-
dom phase approximation treatment of electronic correlations. We find that the compressibility is
strongly suppressed by electron-electron interactions at low carrier densities. Correlations do not
lead to any qualitative new features, but are crucially important for a quantitative understanding
of this fundamental thermodynamic property of graphene bilayers.
