The dynamics of electrons in counter-propagating, circularly polarized laser beams are shown to exhibit attractors whose ability to trap particles depends on the ratio of the beam intensities and a single parameter describing radiation reaction. Analytical expressions are found for the underlying limit cycles and the parameter range in which they are stable. In high-intensity optical pulses, where radiation reaction strongly modifies the trajectories, the production of collimated gamma-rays and…

Anomalous radiative trapping in laser fields of extreme intensity.
TLDR
It is demonstrated that charged particles in a sufficiently intense standing wave are compressed toward, and oscillate synchronously at, the antinodes of the electric field, which provides a mechanism for particle control in high-intensity quantum-electrodynamics experiments.

It is shown that a beam of 10(9) 1 GeV electrons colliding with a 30 fs laser pulse of intensity 10(22)  W cm(-2) will emit 6300 photons with energy greater than 700 MeV, 60× the number predicted by classical theory.

Radiation-reaction trapping of electrons in extreme laser fields.
TLDR
A radiation-reaction trapping (RRT) of electrons is revealed in the near-QED regime of laser-plasma interaction and the threshold of laser field amplitude for RRT is approximately the cubic root of laser wavelength over classical electron radius.
Attractors and chaos of electron dynamics in electromagnetic standing waves
Stochasticity effects in quantum radiation reaction.
TLDR
This work identifies the physical origin of this opposite tendency in the intrinsic stochasticity of photon emission, which becomes substantial in the quantum regime when quantum effects become important, and shows that the energy distribution of the electron beam spreads out after interacting with the laser pulse.
Radiation damping effects on the interaction of ultraintense laser pulses with an overdense plasma.
TLDR
The radiation damping may restrain the maximal energy of relativistic electrons in ultraintense-laser-produced plasmas and the radiation efficiency is shown to increase nonlinearly with laser intensity.
