Critical Temperature of Nuclear Matter

Light clusters in nuclear matter of finite temperature

We investigate properties and the distribution of light nuclei (A ≤ 4) in symmetric nuclear matter of finite temperature within a microscopic framework. For this purpose we have solved few-body Alt-Grassberger-Sandhas type equations for quasi-nucleons that include self-energy corrections and Pauli blocking in a systematic way. In a statistical model we find a significant influence in the compos...

Temperature Dependence of the Effective Interaction in Nuclear Matter

Chiral dynamics of nuclear matter at finite temperature

We extend a recent calculation of nuclear matter in the systematic framework of chiral perturbation theory to finite temperatures T . The contributions from oneand two-pion exchange diagrams which cause nuclear binding and saturation at T = 0 are included for T > 0 in the density and temperature dependent free energy per particle, F̄ (ρ, T ). The calculated pressure isotherms display the familia...

Isovector Collective Response Function of Nuclear Matter at Finite Temperature

We study isovector collective excitations in nuclear matter by employing the linearized Landau-Vlasov equation with and without a non-Markovian binary collision term at finite temperature. We calculate the giant dipole resonance (GDR) strength function for finite nuclei using Steinwedel-Jensen model and also by Thomas-Fermi approximation, and we compare them for 120Sn and 208Pb with experimenta...

Bulk viscosity of QCD matter near the critical temperature

Kubo's formula relates bulk viscosity to the retarded Green's function of the trace of the energy-momentum tensor. Using low energy theorems of QCD for the latter we derive the formula which relates the bulk viscosity to the energy density and pressure of hot matter. We then employ the available lattice QCD data to extract the bulk viscosity as a function of temperature. We find that close to t...
