Title: A New Relativistic Quantum Molecular Dynamics (RQMD) Approach for High-Energy Nuclear Collisions
Abstract: Microscopic transport models such as the Boltzmann-Uehling-Uhlenbeck(BUU) and Quantum Molecular Dynamics (QMD), along with their relativistic extensions, have been widely applied to simulate the space-time evolution of nuclear collisions and to extract properties of dense nuclear matter, such as the equation of state (EoS). These models typically consist of two main components: a Boltzmann-type collision term and mean-field propagation.
In this talk, I will present a new covariant formulation of Relativistic Quantum Molecular Dynamics (RQMD). Key improvements include the implementation of a covariant cascade method for the collision term, and a more reliable estimation of density-dependent potentials, which are essential for constraining the EoS of dense nuclear matter.
