On the elliptical flow in asymmetric collisions and nuclear equation of state

TL;DR

This study uses Quantum Molecular Dynamics simulations to analyze elliptical flow in asymmetric nuclear collisions across various energies, revealing a transition from in-plane to out-of-plane flow and a power-law dependence of flow on fragment mass.

Contribution

It is the first to predict that elliptical flow for different fragments in asymmetric collisions follows a power-law dependence on total mass number.

Findings

Significant change from in-plane to out-of-plane flow with energy

Elliptical flow follows a power-law dependence on fragment mass

Comparison with experimental data validates simulation results

Abstract

We here present the results of elliptical flow for the collision of different asymmetric nuclei (10Ne20 +13 Al27, 18Ar40 +21 Sc45, 30Zn64 +28 Ni58, 36Kr86 +41 Nb93) by using the Quantum Molecular Dynamics (QMD) model. General features of elliptical flow are investigated with the help of theoretical simulations. The simulations are performed at different beam energies between 40 and 105 MeV/nucleon. A significant change can be seen from in-plane to out-of-plane elliptical flow of different fragments with incident energy. A comparison with experimental data is also made. Further, we predict, for the first time that, elliptical flow for different kind of fragments follow power law dependence ? C(Atot)? for asymmetric systems.
