Journal ArticleDOI
Extremely high-intensity laser interactions with fundamental quantum systems
TL;DR: In this article, a review of recent investigations on high-energy processes within the realm of relativistic quantum dynamics, quantum electrodynamics, and nuclear and particle physics, occurring in extremely intense laser fields is presented.
Journal ArticleDOI
Relativistic high-power laser–matter interactions
TL;DR: A review of the recent advances in the field and stresses quantum phenomena that require laser field intensities in excess of the relativistic threshold of ∼ 10 18 W / cm 2 is presented in this article.
Journal ArticleDOI
Quantum radiation reaction effects in multiphoton Compton scattering.
TL;DR: It is demonstrated how in this regime quantum signatures of the radiation reaction strongly affect multiphoton Compton scattering spectra and that they could be measurable in principle with presently available laser technology.

TL;DR: In this paper, the first hundred attoseconds of the electron dynamics during strong field tunneling ionization were investigated and the agreement between experiment and theory provided clear evidence for a nonzero tunneling time delay and a nonvanishing longitudinal momentum of electron at the ''tunnel exit''.
Journal ArticleDOI
Strong Signatures of Radiation Reaction below the Radiation-Dominated Regime
TL;DR: This equilibrium is shown to be far more sensitive to the influence of RR than previously studied scenarios, and can be experimentally investigated with currently available laser systems and the underlying widely discussed theoretical equations become testable for the first time.
