Near-thermal state and thermodynamic response of a QCD system in ultra-central heavy-ion collisions
Yu-Shan Mu, Li Yan, Xu-Guang Huang
We present a systematic framework to extract QCD thermodynamic properties at finite baryon density from ultra-central heavy-ion collisions, where the impact parameter is nearly zer…

Extracting the Speed of Sound in Heavy-Ion Collisions: A Study of Quantum-Initiated Fluctuations and Thermalization
Yu-Shan Mu, Jing-An Sun, Li Yan +1
The thermalization of quark-gluon plasma created in heavy-ion collisions is crucial for understanding its behavior as a relativistic fluid and the thermodynamic properties of the Q…

Relativistic spin hydrodynamics revisited with general rotation by entropy-current analysis
Lixin Yang, Li Yan
We revisit the canonical formulation of spin hydrodynamics for Dirac fermions with a general thermal vorticity. The orders of the general thermal vorticity and the corresponding sp…
