# Deconfinement transition at high isospin chemical potential and low temperature

@article{Cohen2015DeconfinementTA, title={Deconfinement transition at high isospin chemical potential and low temperature}, author={Thomas D. Cohen and Srimoyee Sen}, journal={Nuclear Physics}, year={2015}, volume={942}, pages={39-53} }

Abstract We consider QCD with two degenerate flavors of light quarks (up and down) at asymptotically high isospin ( μ I ) with zero baryon chemical potential ( μ B ) and calculate for the first time a quantitative expression for the critical temperature of the deconfinement transition in this regime. At high isospin chemical potential and sufficiently low temperatures this theory becomes equivalent to a pure Yang–Mills theory and accordingly has a first order deconfinement phase transition…
