Many theories beyond the standard model predict new phenomena
which decay to leptons and jets or purely leptons.
Searches for new physics models with these signatures
are performed using the ATLAS experiment at the LHC.
This paper presents the corresponding searches' results
using the $pp$ collision data sample collected in 2015
and 2016 by the ATLAS detector at the LHC
with a center-of-mass energy of 13 TeV.
