Abstract

I review the main features of our model of the 4-dimensional Yang-Mills theory vacuum as a liquid of fractional instantons. The model provides a possible microscopic mechanism for Confinement in four dimensional Yang-Mills theory at T=0. It also connects this property to other non-perturbative properties of the theory which can be explained by the same model. This paper is a, somewhat enlarged, written up version of my recent talks on the subject given at ICTS-Bangalore, KITP-Santa Barbara and IMSC-Chennai.
