Charged particle in Lie–Poisson electrodynamics

open access: yesEuropean Physical Journal C: Particles and Fields
Lie–Poisson electrodynamics describes the semi-classical limit of non-commutative U(1) gauge theory, characterized by Lie-algebra-type non-commutativity. We focus on the mechanics of a charged point-like particle moving in a given gauge background. First,
