EE Seminar #13: Fabien Paillusson – Spectroscopic classification of non-ergodic populations

Non-ergodicity impacts statistical inference across a diverse range of disciplines, both within and beyond physics. However, the concept of ergodicity is used inconsistently and may refer to several non-equivalent notions.

In this talk, Fabien Paillusson (University of Lincoln) identifies and clarifies the relationships between three major interpretations of ergodicity. Furthermore, he introduces a method based on spectral analysis that can be used to identify, quantify, and classify non-ergodic populations within an ergodic decomposition. The method is demonstrated through an application to the Kob–Andersen kinetically constrained lattice glass model.

The talk is based on joint work with Nicolas Underwood, published in a working paper available here.

This is an online event. We look forward to seeing you there!
