Query: Nuclear dynamics and particle production near threshold energies in
  heavy-ion collisions   Recent progress of the quantum molecular dynamics model for describing the
dynamics of heavy-ion collisions is viewed, in particular the nuclear
fragmentation, isospin physics, particle production and in-medium effect,
hadron-induced nuclear reactions, hypernucleus etc. The neck fragmentation in
Fermi-energy heavy-ion collisions is investigated for extracting the symmetry
energy at subsaturation densities. The isospin effects, in-medium properties
and the behavior of high-density symmetry energy in medium and high energy
heavy-ion collisions are thoroughly discussed. The hypernuclide dynamics formed
in heavy-ion collisions and in hadron induced reactions is analyzed and
addressed in the future experiments at the High-Intensity heavy-ion Accelerator
Facility (HIAF).
