Title: "Superstatistics: A Universal Framework for Nonequilibrium Phenomena"

10/22/2025
4 pm – 5 pm
Wilder 202 and on Zoom
Intended Audience(s): Public
Categories: Lectures & Seminars, School of Arts and Sciences

Abstract: Non-Maxwellian distributions are commonplace in many systems—from space plasmas and self-gravitating systems to controlled experimental settings. In this talk, I introduce the concept of superstatistics, which captures the statistical properties of such systems as a superposition of statistics. I outline the key principles of the formalism and present its applications to space plasmas, gravitational systems, and magneto-optical traps. I then turn to recent advances in understanding the relaxation of nonequilibrium systems within the superstatistical approach. Finally, I discuss how these non-Maxwellian distributions might be exploited to enhance reactivity in fusion processes.
