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 …

The petawatt (PW) laser facility of the Berkeley Lab Laser Accelerator (BELLA) Center has
recently commissioned its second laser pulse transport line. This new beamline can be …

Strong-field quantum electrodynamics (SFQED) processes are central in determining the
dynamics of particles and plasmas in extreme electromagnetic fields such as those present …

Processes occurring in the strong field regime of QED are characterized by background
electromagnetic fields of the order of the critical field F cr= m 2 c 3/ℏ| e| in the rest frame of …

Available laser technology is opening the possibility of testing QED experimentally in the so-
called strong-field regime. This calls for develo** theoretical tools to investigate strong …

We demonstrate experimentally that the trident process e-→ e-e+ e-in a strong external field,
with a spatial extension comparable to the effective radiation length, is well understood …

We report on the observation of thermal photons from an accelerated electron via
examination of radiative beta decay of free neutrons measured by the RDK II collaboration …

An accelerated charged particle emits electromagnetic radiation. If the driving force is
sufficiently strong, the radiated energy becomes comparable to the kinetic energy of the …
