Generalized Beth--Uhlenbeck entropy formula from the derivable approach
David Blaschke, Gerd Röpke, Gordon Baym
We derive a generalized Beth-Uhlenbeck formula for the entropy of a dense fermion system with strong two-particle correlations, including scattering states and bound states. We wor…

Medium effects on freeze-out of light clusters at NICA energies
G. Roepke, D. Blaschke, Yu. B. Ivanov +3
We estimate the chemical freeze-out of light nuclear clusters for NICA energies of above 2 A GeV. On the one hand we use results from the low energy domain of about 35 A MeV, where…
