A Frenet-Serret Interpretation of Particle Dynamics in High-Intensity Laser Fields

Understand

In this paper we discuss the dynamics of charged particles in high-intensity laser fields in the context of the Frenet-Serret formalism, which describes the intrinsic geometry of particle worldlines.

• We find approximate relations for the Frenet-Serret scalars and basis vectors relevant for high-intensity laser particle interactions.
• The onset of quantum effects relates to the curvature radius of classical trajectories being on the order of the Compton wavelength.
• The effects of classical radiation reaction are discussed, as well as the classical precession of the spin-polarization vector according to the Thomas-Bargman-Michel-Telegdi (T-BMT) equation.
