We present the comprehensive interpretation of the momentum distribution of nucleons participating in different kinds of nuclear flow, within the framework of isospin-dependent quantum molecular dynamics (IQMD) model. Our study reveals that the number of nucleons decreases with increasing order of different harmonics ⟨v1⟩, ⟨v2⟩, ⟨v3⟩, and ⟨v4⟩. The magnitude of flow harmonics depends strongly on transverse momentum.

Space Analysis

Using the isospin dependent quantum molecular dynamics model, we study the phase space distribution of the nucleons coming from participant matter that are contributing in flow. The distribution of nucleons and fragments is not symmetric around the beam axis. Our study shows that the nucleon which suffer maximum number of collisions are contributing in anisotropic flow.

We present a complete systematic theoretical study of the multifragmentation for asymmetric colliding nuclei in heavy-ion reactions in the energy range between 50 and 1000 MeV/nucleon by using the isospin-dependent quantum molecular dynamics (IQMD) model. We have observed an interesting outcome for asymmetric colliding nuclei. The comparison between the symmetric and asymmetric colliding nuclei for the isospin-independent and isospin-dependent cross sections has been performed. We have found the pronounced effect of different cross sections and mass asymmetry on the nuclear reaction dynamics.

AbstractThe sound velocities of water in the Hugoniot states are investigated by laser shock compression of precompressed water in a diamond anvil cell. The obtained sound velocities in the off-Hugoniot region of liquid water at precompressed conditions are used to test the predictions of quantum molecular dynamics (QMD) simulations and the SESAME equation-of-state (EOS) library. It is found that the prediction of QMD simulations agrees with the experimental data while the prediction of SESAME EOS library underestimates the sound velocities probably due to its improper accounting for the ionization processes.
