When quantum materials are highly excited by ultrafast lasers, the electrons exchange energy with phonons and eventually the system relaxes back to equilibrium at a well known temperature. But the precise pathway tha the system uses to get there is a question that continues to elude us from a concrete answer. In a recent PRX article, Prof. Freericks and collaborators at North Carolina State University show that many of the common assumptions people have used to analyze these problems are wrong! The article provides a fresh new perspective for how one should analyze these types of problems including an analogy with a "quantum Cheshire Cat".
