What do people mean by "dynamical phase transition"?

SUMMARY

The term "dynamical phase transition" refers to a concept introduced by M. Heyl, A. Polkovnikov, and S. Kehrein in their 2013 paper published in Physical Review Letters (Phys. Rev. Lett. 110, 135704). This concept does not denote a unique phenomenon, as it varies based on the context in which it is applied. The authors discuss multiple interpretations and meanings of the term, particularly in relation to control parameters, emphasizing the need for clarity regarding the specific context being referenced.

PREREQUISITES
  • Understanding of phase transitions in statistical mechanics
  • Familiarity with control parameters in physical systems
  • Knowledge of dynamical systems theory

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

It doesn't denote a unique phenomenon. Which context do you refer to?

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.
