Query: On the Phase Diagram of QCD with Small Isospin Chemical Potential   The regime of small isospin chemical potential in QCD is investigated. Using
the phase quenched partition function in the $\epsilon$-regime an expression
for the chiral condensate is given, which is studied in the temperature isospin
chemical potential plane. Lines of constant values of the condensate are shown
and it is estimated how the critical temperature varies as a function of the
isospin chemical potential. Finally, the dependency of the fermion sign problem
on the chemical potential and temperature is examined.
