Measurements of asymmetries in top-quark production and tests of lepton universality in ATLAS

The top quark is the heaviest known fundamental particle. As it is the only quark that decays without hadronisation, it provides the unique opportunity to probe the properties of bare quarks at the Large Hadron Collider (LHC). This article will present two recent measurements of the top quark using 13 TeV collision data with the ATLAS experiment: the top and anti-top quark pair ($t\bar{t}$) charge asymmetry measurement alongside the first test of lepton flavour universality (LFU) of leptons to $W$ bosons from $t\bar{t}$ events.
