Colloquia

These lectures feature speakers from around the country and globe. Each colloquium lasts about an hour and gives you a deeper understanding of physics and astronomy research taking place around the world.

Colloquia will be held in a hybrid format. A recurring Zoom link is available for virtual attendance.

Talks are held on Thursdays at 4:15 p.m. in the Rogers Room (Jones PSC 409), unless stated otherwise.

To be added to the email distribution list for upcoming colloquia, contact Ms. Nancy Kesar at nkesar@mailbox.sc.edu.

Upcoming Colloquium

Particle Acceleration in Turbulence

Speaker: Dr. Siyao Xu
Affiliation: University of Florida
Date: October 01, 2026

Abstract:

Energetic particle transport and acceleration in turbulent plasmas are central to many problems in space and astrophysics. Traditional stochastic-scattering theories tend to isotropize particle pitch angles, while observations and simulations find strongly anisotropic accelerated particles. In this talk, I will present our recent work on a new particle acceleration mechanism driven by temporal variations in magnetic-field strength and the induced electric fields arising from Faraday’s law. I will discuss the numerical testing of this theory using first-principles kinetic simulations and its implications for particle acceleration in turbulent astrophysical plasmas.
