The quantum entropy at finite temperatures is analyzed by using models for colored quarks making up the physical states of the hadrons. We explicitly work out some special models for the structure of the states of SU(2) and SU(3) relating to the effects of the temperature on the quantum entropy. We show that the entropy of the singlet states monotonically decreases meaning that the mixing of th...

Previously we identified the receding flow, where two fluid streams recede from each other, as an open numerical problem,1 because all well-known numerical fluxes give an anomalous temperature rise, thus called the overheating problem. This phenomenon, although presented in several textbooks,2,3 and many previous publications, has scarcely been satisfactorily addressed and the root cause of the...
