Asymptotic Freedom and Color Superconductivity in Dense Quark Matter
The current view that QCD predicts an approximately free quark-gluon gas phase at high densities and temperatures, which is incompatible with the kind of non-perturbative confinement effects that would be needed to yield a limiting Hagedorn temperature at high densities.
The recent suggestion of my student, Bertrand Barroisl1, that QCD leads to a different kind of non-perturbative phase, analogous to superconductivity, at high densities and low temperatures.
