abstract

We study the kinematic and thermal vorticities in low-energy heavy-ion collisions by using the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model. We explore their time evolution and spatial distribution. We find that the initial vorticities have a non-monotonic dependence on the collision energy $\sqrt{s_{\rm NN}}$: as $\sqrt{s_{\rm NN}}$ grows the vorticities first increase steeply and then decrease with the turning point around $\sqrt{s_{\rm NN}}\sim 3-5$ GeV depending on the centrality.

    nucl-th 2026-03 conditional novelty 6.0 of 10

    In AMPT and UrQMD simulations, fluid acceleration in heavy-ion collisions reaches a few hundred MeV, peaks at fireball boundaries, and evolves from stopping-dominated deceleration at low energies to boundary/tilt puls...

    nucl-th 2025-06 conditional novelty 5.0 of 10

    Nucleon-nucleon scatterings with phase-shift-derived spin changes and rigorous angular momentum conservation generate 1-2% spin polarization in intermediate-energy heavy-ion collisions.

    At one loop, imaginary rotation in the SU(2) Savvidy model enhances the chromomagnetic condensate and effective coupling, can suppress the Nielsen-Olesen instability in a finite window, and gives a negative moment-of-...
