### Search for physics beyond the Standard Model with top quarks at ATLAS.

Philippe Calfayan
This document reports on recent searches for new physics involving top quarks in proton-proton collisions at the center-of-mass energy $\sqrt{s}=\unit{7}{\TeV}$. Analyses using data samples with integrated luminosities up to \unit{2}{\invfb} recorded with the ATLAS detector are presented.
