Measurement of top-quark cross sections and properties with the ATLAS detector at the LHC

The remarkably large integrated luminosity collected by the ATLAS detector at the highest proton-proton collision energy provided by LHC allows to use the large sample of top quark events to test theoretical predictions with unprecedented precision. Using data taken with the ATLAS detector at the LHC, recent measurements of total and differential top-quark cross sections as well properties of top-quark production are shown, including in particular a new measurement of the spin polarisation in single-top-quark production, and new measurements that promise to improve Monte Carlo predictions.
