Description
QCD matter exhibits a variety of nontrivial static and dynamical phenomena under external fields. While electromagnetic fields are well-known examples, recent studies have suggested that curved spacetime can also act as an external gravitational background for quantum matter and significantly affect its phase structure.
Motivated by these developments, we address a rather fictitious but intriguing question: What would happen to QCD matter in an extremely rapidly expanding universe?
In this talk, I will present our recent progress toward answering this question. In particular, I will discuss how rapid cosmic expansion affects QCD matter and present our latest results.
