Abstract

The dynamics and radiation of positronium are investigated in intense laser fields. Our two-body quantum mechanical treatment displays the tunneling, free-evolution, and recollision dynamics of electron and positron in both the oscillating laser electric and laser magnetic field components. In spite of significant momentum transfer of the numerous incoming laser photons, recollisions of both particles are shown to occur automatically after tunneling ionization, along with substantial x-ray and gamma-ray emission during recombination and annihilation processes.
