abstract
We study the extension of a phenomenologically successful quasiparticle model that describes lattice results of the equation of state of the deconfined phase of QCD for Tc <= T < 4 Tc, to finite quark chemical potential mu. The phase boundary line Tc(mu), the pressure difference (p(T,mu)-p(T,mu=0))/T^4 and the quark number density nq(T,mu)/T^3 are calculated and compared to recent lattice results. Good agreement is found up to quark chemical potentials of order mu = Tc.

Constraint on the magnetic field for the stable strange quark matter
A quasiparticle model predicts a lower limit on the magnetic field required for absolutely stable strange quark matter, with the limit rising as quark coupling and vacuum bag constant increase.
