# Phase diagram of QCD and pion condensation

## Jens Andersen (NTNU Trondheim)

I will discuss various aspects of the QCD phase diagram, in particular pion
condensation at finite isospin chemical potential. I will present our recent
calculation of the thermodynamic functions in the pion-condensed phase at
next-to-leading order using chiral perturbation theory. At finite isospin
chemical potential, but zero baryon chemical potential, there is no sign
problem in QCD and the system is amenable to lattice simulations.I will
compare our calculations with recent precision lattice simulations and
discuss applications of the equation of state to pion stars.
