Title: On the motion of charged particles in a constant electromagnetic field

Time&Venue: 2025年5月13日（星期二）10:00-11:00 & S325

Abstract:  In this talk, we present a rigorous mathematical derivation for the classical phenomenon in Maxwell's theory that a charged particle moves along a straight line in a constant electromagnetic field if the initial velocity is parallel to the constant electromagnetic field. The particle is modeled by scaled solitons to a class of nonlinear Klein-Gordon equations. We show that the soliton is stable up to any given time. This is based on joint work with Shuang Miao and Pin Yu.
