I heard of it several times in colloquiums. But I still cannot grasp the meaning. What is the control parameter in this phase transition?

One meaning of the term was introduced in
M. Heyl, A. Polkovnikov, and S. Kehrein, Phys. Rev. Lett. 110, 135704 (2013);
they mention several other meanings of the term in the second last paragraph of p.4.
