Third generation SUSY searches in ATLAS

Supersymmetry (SUSY) is one of the most popular and promising extensions to the Standard Model (SM) of particle physics. It predicts partner particles for all SM particles with a spin difference of $1/2$. These SUSY partners, if they exist within a reachable energy scale, should be produced at the Large Hadron Collider (LHC). The events are usually characterized by high missing transverse energy and can have varying jet and lepton multiplicities, depending on the model used. Searches for partners of third generation squarks are of special interest because of their special event topologies.\\ Many searches have been performed in proton-proton collisions at $\sqrt{s}=13$ TeV at the LHC with the ATLAS detector, using an integrated luminosity of $3.2$ fb$^{-1}$. Several of these will be presented in these proceedings.\\ No significant deviations from the SM expectations have been observed and exclusion limits have been set for the respective models. Most analysis already exceed the sensitivity achieved with Run1 analysis.
