In 7 TeV proton-proton collisions at the LHC, pairs of top and anti-top quarks are expected to be mostly produced through gluon fusion, in contrast to production at the Tevatron, where quark annihilation dominates. The ATLAS experiment has now recorded a large number of top quark pairs, allowing this domain to be explored in detail. In this seminar we will present precision measurements of the top quark pair production cross-section and of properties of the top quark pair system, including the ttbar charge asymmetry and the ttbar spin correlation. Top quark pairs are also studied in the context of additional QED/QCD radiation or searches for exotic particles.
