We study the perturbative evolution of a jet via multiple gluon emissions induced by the interactions between the jet constituents and a dense QCD medium like a quark-gluon plasma. We focus on the typical medium-induced gluon emissions, for which the gluon formation time is much smaller than the overall size of the medium. We show that the typical time between two subsequent emissions is...

The quark gluon plasma thermalization in heavy ion collisions is an open problem that gave rise to many works in recent years. One of the approaches developped to study this QCD non pertubative problem is a resummation scheme that amounts to averaging over classical fields with random initial conditions. Its numerical implementation is presented here in the case of a scalar field theory with a...

12. Symmetries and currents of the ideal and the unitary Fermi gases

The maximal algebra of symmetries of the free Schrodinger equation is determined. This algebra is an infinite dimensional extension of the Schrodinger algebra (by higher symmetries which are not kinematical transformations), it is isomorphic to the Weyl algebra of quantum observables, and it may be interpreted as a non-relativistic higher-spin algebra. The associated infinite collection of...
