Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This …

The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

Charged particles accelerated by electromagnetic fields emit radiation, which must, by the
conservation of momentum, exert a recoil on the emitting particle. The force of this recoil …

Spin polarization of an ultrarelativistic electron beam head-on colliding with an ultraintense
laser pulse is investigated in the quantum radiation-dominated regime. We develop a Monte …

Since the invention of chirped pulse amplification, which was recognized by a Nobel Prize in
physics in 2018, there has been a continuing increase in available laser intensity. Combined …

The generation of ultrarelativistic polarized positrons during the interaction of an
ultrarelativistic electron beam with a counterpropagating two-color petawatt laser pulse is …

The investigation of spin and polarization effects in ultra-high intensity laser–plasma and
laser–beam interactions has become an emergent topic in high-field science recently. In this …

Generation of ultrarelativistic polarized leptons during interaction of an ultrarelativistic
electron beam with a counterpropagating ultraintense laser pulse is investigated in the …

In a previous paper we showed how higher-order strong-field-QED processes in long laser
pulses can be approximated by multiplying sequences of'strong-field Mueller matrices'. We …

Here, we demonstrate the radiative polarization of high-energy electron beams in collisions
with ultrashort pulsed bichromatic laser fields. Employing a Boltzmann kinetic approach for …
