Abstract
Using the local density approximation and its combination with dynamical mean field theory, we show that electronic correlations induce a single sheet cuprate-like Fermi surface for LaNiO{sub 3}/LaAlO{sub 3} heterostructures, even though both e{sub g} orbitals contribute to it. This is possible because the correlations shift one of the two sheets above the Fermi level. As there are also strong antiferromagnetic fluctuations, the low-energy electronic and spin excitations resemble those of high-temperature cuprate superconductors.
