Abstract

Isospin quantum molecular dynamics (IQMD) model is a reliable computational tool for the study of various phenomena (multi fragmentation, anisotropic flow, nuclear stopping) from low to intermediate heavy ion collisions. Here, simulation has been carried out for the magnetic field generated during non-central heavy ion collisions using the IQMD model. The effect of various parameters, such as centrality, angular momentum, rapidity and incident energy has been thoroughly investigated on the magnetic field with the evolution of time and space. It has been observed that the rapidity bin significantly impacts the magnitude of the magnetic field in different directions. Furthermore, the magnetic field produced during heavy ion collision (HIC) leads to a notable impact on the in-plane momentum of the proton and neutron.

跃迁能附近重离子碰撞产生的磁场

等自旋量子分子动力学（IQMD）模型是研究从低到中等重离子碰撞的各种现象（多碎片、各向异性流动、核停止）的可靠计算工具。在此，使用IQMD模型对非中心重离子碰撞过程中产生的磁场进行了模拟。随着时间和空间的演化，深入研究了中心性、角动量、速度和入射能量等各种参数对磁场的影响。已经观察到，快速度仓在不同方向上显著影响磁场的大小。此外，重离子碰撞（HIC）过程中产生的磁场对质子和中子的面内动量产生了显著影响。
