Abstract: The boiling of possible quark nuggets during the quark-hadron phase transition of the early Universe at nonzero chemical potential is revisited. For the hadron phase the microscopic Brueckner-Hartree-Fock approach is employed; For the deconfined phase of quark matter, we use a recently developed quark mass density-dependent model with a fully self-consistent thermodynamic treatment of confinement. Results are discussed in relation to the recent lattice QCD calculations of the vacuum chiral condensate, including the potential consequences on the possibility of quark nuggets as a candidate of dark matter.
