Polaritons are formed by the strong coupling of light and matter. When they mix together, all the matter is excited simultaneously—referred to as delocalization. This delocalization has the unique ability to relay energy between matter that is otherwise not possible.

Disordered energy is ubiquitous in nature and the universe. Disordered energy is less organized and less available to do work, such as with heat dissipation. Even in plants, disorder can ruin effective energy transfer.

In the context of polaritons, as disorder increases, it can negatively affect light-matter interactions, including polariton-enabled energy transfers. Overcoming this disorder is an important topic across many scientific fields.
