The physics of quantum degenerate gases with dipolar interactions is emerging as an active area of research in the field of ultracold atoms. Experimental efforts are following both the route of cooling atomic species with a large magnetic moment, such as Dysprosium and Erbium, and the one of producing heteronuclear molecules in their ground state which exhibit a large electric dipole moment. From the theoretical point of view, very peculiar and interesting many-body effects are expected in the regime where dipolar interactions dominate. I will review some recent work carried out using quantum Monte Carlo methods on the various phases of dipolar bosons and fermions in single and bilayer geometries. In particular, I will discuss in some details the Fermi liquid to Wigner crystal transition of a Fermi gas in two dimensions and the single-particle to pair superfluid transition in a bilayer system of dipolar bosons.
