"Scarring", the enhancement or suppression of eigenfunction intensity
of a quantized chaotic hamiltonian near unstable periodic orbits, is a
well-known phenomenon in closed systems. We study scarring effects in
non-hermitian hamiltonians, meaning in the presence of losses. In particular,

we investigate the decay of correlations, the distributions of the
amplitudes of the eigenstates, and their dependence on the amount of
loss and location of the opened region in the phase space of a
kicked-rotor type of system.
