Sensitivity of the transverse flow towards symmetry energy

We study the sensitivity of transverse flow towards symmetry energy in the Fermi energy region as well as at high energies. We find that transverse flow is sensitive to symmetry energy as well as its density dependence in the Fermi energy region. We also show that the transverse flow can address the symmetry energy at densities about twice the saturation density, however it shows the insensitivity towards the symmetry energy at densities $ρ/ρ_{0}$ $>$ 2. The mechanism for the sensitivity of transverse flow towards symmetry energy as well as its density dependence is also discussed.

Geometry of vanishing flow: a new probe to determine the in-medium nucleon nucleon cross-section

We study the transverse flow throughout the mass range from $^{20}Ne+^{20}Ne$ to $^{131}Xe+^{131}Xe$ as a function of the impact parameter. We find that at smaller impact parameters the flow is negative while going through the impact parameter, transverse flow vanishes at a particular colliding geometry named GVF. We find that the mass dependence of GVF is insensitive to the equation of state and momentum dependent interactions whereas it is quite sensitive to the cross section. So it can act as a useful tool to pin down the nucleon nucleon cross section.

Impact parameter dependence of isospin effects on the mass dependence of balance energy

We study the effect of isospin degree of freedom on the balance energy as well as its mass dependence throughout the mass range 48-270 for two sets of isobaric systems with N/Z = 1 and 1.4 using isospin-dependent quantum molecular dynamics (IQMD) model. Our fndings reveal the dominance of Coulomb repulsion in isospin effects on balance energy as well as its mass dependence throughout the range of the colliding geometry.

Study of Participant-Spectator Matter at the Energy of Vanishing Flow

We aim to study the participant-spectator matter over a wide range of energies of vanishing flow and masses. For this, we employed different model parameters at central and semi-central colliding geometries. Remarkably, a nearly mass independent nature of the participant matter was obtained at the energy of vanishing flow. This makes it a very strong alternative candidate to study the energy of vanishing flow. We also show that the participant matter can also act as an indicator to study the degree of thermalization. The degree of thermalization reached in central collisions is nearly the same for different colliding nuclei at the energy of vanishing flow.
