Query: How nuclear jets form and disintegrate into clusters in heavy-ion
  collisions   The most extreme deformations that can be explored in heavy-ion collisions at
Fermi-energies are collimated flows of nuclear matter which recall jet
dynamics.
  From microphysics to the cosmological scale, jets are rather common
topologies.
  In nuclear physics, pioneering works focused on the breakup of these
structures, resulting into early nuclear-fission models in analogy to the
droplet formation in viscous liquids; such view became emblematic to explain
surface-energy effects and surface instability by analogy with the Rayleigh
instability.
  Through a dynamical approach based on the Boltzmann-Langevin equation, well
adapted to out-of-equilibrium conditions, we explored the possibility that
nuclear jets could arise in heavy-ion collisions from different conditions than
those leading to fission or neck fragmentation, and that they can breakup from
mechanisms that are almost unrelated to cohesive properties.
