Description
In 1999, Joe Minahan did very interesting work aimed at finding QCD-like physics from gauge/gravity duality, i.e. deriving the asymptotic freedom and confinement. Somewhat later, the warped deformed conifold background was found, and it incorporates confinement and dimensional transmutation. The corresponding gauge theory is not asymptotically free, but it exhibits logarithmic running in the UV. I will then switch to 1+1 dimensions and show that the two-flavor Schwinger model with the theta-angle equal to pi has QCD-like features as well. In the regime where the fermion mass is much smaller than the gauge coupling, the mass gap becomes exponentially small due to the dimensional transmutation.
