# How superlocalization affects Vibrational Energy Exchange process in proteins

## TL;DR

This paper investigates how superlocalization influences vibrational energy exchange in proteins, revealing that energy diffuses mainly through non-bonded contacts rather than backbone interactions, supported by experimental and computational evidence.

## Contribution

It introduces a theoretical and computational framework explaining the superlocalized nature of backbone motions versus localized non-bonded contacts in proteins.

## Key findings

- Vibrational energy diffuses mainly through non-bonded contacts.
- Backbone motions exhibit superlocalized decay with distance.
- Non-bonded contacts show simple localization behavior.

## Abstract

Recent experimental findings on a protein showed the diffusion of vibrational energy does not occur along the backbone interaction,as it might be expected, but prevalently on non-bonded contacts. These results are explained presenting a theoretical picture, supported by computational calculations, that accounts for these different behaviors in vibrational energy exchange process showing the collective motions on the backbone present a $superlocalized$ nature as their decay with the distance $r$ is $exp(-r^{d})$ with $d \sim 1.8$, whereas those associated to non-bonded contacts result simply localized with $d \sim 1$.
