Under the relaxation time approximation of the Boltzmann equation, we compute the viscosities of the system to leading power in $T/\mu_B$ expansion and establish a relation between the thermodynamic potential and transport coefficients, including bulk viscosity ($\zeta$) and shear viscosity ($\eta$). It is found that hydrodynamic stability ($\zeta>0$) imposes additional constraints on the thermodynamic potential. As an example, these relations are applied to the Walecka model. The fluid properties of the cold and dense nucleon matter are characterized by the dimensionless combination of viscosities times the quasi-Fermi momentum over the enthalpy. Furthermore, we discuss the implication of the stability condition on the range of applicability of the model.

Title: Effects of Initial Nucleon-Nucleon Correlations on Light Nuclei Production in Au+Au Collisions at $\sqrt{s_{NN}}$=3 GeVSpeaker: Qian-Ru LinTime: 21 March (Friday) 2025, 2:00 pmLocation: 9627Abstract: Light nuclei production in heavy-ion collisions serves as a sensitive probe of the QCD phase structure. In coalescence models, triton (Nt) and deuteron (Nd) yields depend on the spatial separation ...
