Title: The Connection Between Spin and the QCD Phase Transition
Abstract: In high-energy nuclear physics, large angular momentum can arise in non-
central heavy-ion collisions, resulting in a rapidly rotating quark-gluon plasma (QGP). In
recent years, the effects of rotation have attracted growing interest from both theoretical
and experimental perspectives. In this talk, I will present recent progress on the QCD
phase diagram under rotation, with a particular focus on its possible connection to spin
phenomena in heavy-ion collisions. Although these two aspects have been extensively
studied individually, their interrelation remains insufficiently explored. I will mainly discuss
one specific possibility — the quark–antiquark spin correlations near the QCD critical end
point (CEP) — and how such correlations may provide new insights into critical dynamics.
I will also briefly touch on the role of polarized gluon fields under rotation, which is
potentially related to this topic.
Brief introduction about the speaker: Hao-Lei Chen is currently a postdoctoral researcher
in physics at Fudan University. He obtained his B.S. degree in 2015 from East China
Normal University and his Ph.D. in 2020 from Fudan University. His research interests
mainly focus on rotational effects on chiral symmetry breaking and confinement in QCD,
and further, how these effects manifest in experimental observables such as spin
polarization and spin alignment in heavy-ion collisions.
