What is it about?
In this paper, we use an advanced real-time time-dependent density functional theory quantum simulation to show that the atomic dynamics of order and disorder in photo-induced phase transitions depend strongly on the competition between deterministic motions caused by photocarriers and random vibrations caused by heat.

Why is it important?
We learn more about the microscopic mechanism of photo-induced phase transition by unifying the theory of order and disorder dynamics.
Perspectives
I hope that this article has given you some ideas about how to use light to control materials in a precise way.
