In the context of the longitudinally boost-invariant Bjorken flow with transverse expansion, we use three different numerical methods to analyze the emergence of attractor solution…
Cross-conductivity: novel transport coefficients to constrain the hadronic degrees of freedom of nuclear matter
Jean-Bernard Rose, Moritz Greif, Jan Hammelmann +4
In general, the constituents of the bulk matter produced in heavy-ion collisions carry, besides electric charge, multiple other conserved quantum numbers like baryon number and str…
