QCD phase structure at finite isospin chemical potential and smaller-than-physical quark mass
Bastian B. Brandt, Volodymyr Chelnokov, Francesca Cuteri +1
Introduction of a nonzero isospin chemical potential in QCD leads to the emergence of a pion condensed phase at sufficiently large , bounded by a second order transition line…

Pion condensation at non-zero isospin chemical potential with Wilson fermions
Rocco Francesco Basta, Bastian B. Brandt, Francesca Cuteri +2
In contrast to the case of non-zero baryon chemical potential, the isospin chemical potential does not introduce a sign problem and can be simulated on the lattice. When the isospi…

Condensation of lighter-than-physical pions in QCD
Bastian B. Brandt, Volodymyr Chelnokov, Francesca Cuteri +1
We report on the results of the 2+1 flavour QCD simulations at nonzero isospin chemical potential performed at half the physical light quark mass. At low temperatures and large iso…
