  We present a new model for jet quenching from coherent radiation in a brick
medium. The jet energy loss is simulated as a perturbative final-state vacuum
parton shower followed by a medium-induced shower originating from elastic and
radiative collisions with the medium constituents. Coherency is achieved by
starting with trial gluons that act as field dressing of the initial jet
parton. These are formed according to a Gunion-Bertsch seed. The QCD version of
the LPM effect is attained by increasing the phase of the trial gluons through
elastic scatterings with the medium. Above a phase threshold, the trial gluons
will be realised and can produce coherent radiation themselves. The model has
been implemented in a Monte Carlo code and has been validated by successfully
reproducing the BDMPS-Z prediction for the energy spectrum. The realistic case
with minimal assumptions are also produced and shown. In particular, we show
the influence of various parameters on the energy spectrum and transverse
momentum distribution, such as the in-medium quark masses, the energy transfer
in the recoil process, and the phase accumulation criteria, especially for low
and intermediate energy gluons. Future studies will allow for the interface
with full simulations of the quark-gluon-plasma with hydrodynamic evolution,
such as vHLLE, along with subsequent hadronisation of the jet partons in order
to produce realistic distributions that can be directly compared to LHC and
RHIC data.
