We propose that the dynamics of supercooled liquids and the formation of glasses can be
understood from the existence of a zero-temperature dynamical critical point. To support our
proposal, we derive a dynamic field theory for a generic kinetically constrained model, which
we expect to describe the dynamics of a supercooled liquid. We study this field theory using
the renormalization group (RG). Its long time behavior is dominated by a zero-temperature
critical point, which for d> 2 belongs to the directed percolation universality class. Molecular …

We propose that the dynamics of supercooled liquids and the formation of glasses can be
understood from the existence of a zero temperature dynamical critical point. To support our
proposal, we derive from simple physical assumptions a dynamic field theory for
supercooled liquids, which we study using the renormalization group (RG). Its long time
behaviour is dominated by a zero temperature critical point, which for dimensions d> 2
belongs to the directed percolation universality class. Molecular dynamics simulations …
