QCD at nonzero isospin asymmetry

Understand

We study the phase diagram and the thermodynamic properties of QCD at nonzero isospin asymmetry at physical quark masses with staggered quarks.

• In particular, continuum results for the phase boundary between the normal and the pion condensation phases and the chiral/deconfinement transition are presented.
• Our findings indicate that the pion condensation phase is restricted to $T\lesssim170$~MeV for isospin chemical potentials up to 325~MeV.
• We also use the data to test the range of validity of the Taylor expansion method and show first results for the equation of state.
