From a theoretical point of view, what has been the most successful approach to understanding jamming phenomena?
I understand there's still a lot of debate around this subject, namely whether a glass transition is really a phase transition, is jamming just a kinetic arrest of the system or is there anything fundamentally different between a jammed state and an amorphous solid, or even, is there a unified understanding of jammed states among different systems (polymers, granular, colloidal,...).
So in this view, this question is just to find out if in the recent years any game-changing understanding of jamming has arisen.
