Query: Probing chemical freeze-out criteria in relativistic nuclear collisions
  with coarse grained transport simulations   We introduce a novel approach based on elastic and inelastic scattering rates
to extract the hyper-surface of the chemical freeze-out from a hadronic
transport model in the energy range from E$_\mathrm{lab}=1.23$ AGeV to
$\sqrt{s_\mathrm{NN}}=62.4$ GeV. For this study, the Ultra-relativistic Quantum
Molecular Dynamics (UrQMD) model combined with a coarse-graining method is
employed. The chemical freeze-out distribution is reconstructed from the pions
through several decay and re-formation chains involving resonances and taking
into account inelastic, pseudo-elastic and string excitation reactions. The
extracted average temperature and baryon chemical potential are then compared
to statistical model analysis. Finally we investigate various freeze-out
criteria suggested in the literature. We confirm within this microscopic
dynamical simulation, that the chemical freeze-out at all energies coincides
with $\langle E\rangle/\langle N\rangle\approx1$ GeV, while other criteria,
like $s/T^3=7$ and $n_\mathrm{B}+n_\mathrm{\bar{B}}\approx0.12$ fm$^{-3}$ are
limited to higher collision energies.
