      abstract     = {A search for single top-quark production via flavour
                      changing neutral current processes from gluon plus up- or
                      charm--quark initial states in proton--proton collisions at
                      the LHC is presented. Data collected with the ATLAS detector
                      in 2012 at a centre-of-mass energy of 8 TeV and
                      corresponding to an integrated luminosity of 20.3
                      $\mbox{fb}^{-1}$ are used. Candidate events for a top quark
                      decaying into a lepton, a neutrino and a jet are selected
                      and classified into signal- and background-like candidates
                      using a neural network. No signal is observed and an upper
                      limit on the production cross-section multiplied by the $t
                      \rightarrow Wb$ branching fraction is set. The observed 95
                      \% CL limit is $\sigma_{qg \rightarrow t} \times B(t
                      \rightarrow Wb)< 3.4$ pb and the expected 95\% CL limit is
                      $\sigma_{qg \rightarrow t} \times B(t \rightarrow Wb)< 2.9$
                      pb. The observed limit can be interpreted as upper limits on
                      the coupling constants of the flavour changing neutral
                      current interactions divided by the scale of new physics
                      $\kappa_{ugt}/\Lambda < 5.8 \times 10^{-3}$ TeV$^{-1}$ and
                      $\kappa_{cgt}/\Lambda < 13 \times 10^{-3}$ TeV$^{-1}$ and on
                      the branching fractions $B(t \rightarrow ug) < 4 \times
                      10^{-5}$ and $B(t \rightarrow cg) < 17 \times 10^{-5}$.},
