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
Atomic physics with super-high intensity lasers
TL;DR: In this article, the authors review the phenonomena which occur in multiphoton physics when the electric field of the applied laser radiation becomes comparable with the Coulomb field strength seen by an electron in the ground state of atomic hydrogen.
Journal ArticleDOI
Lorentz Meets Fano in Spectral Line Shapes: A Universal Phase and Its Laser Control
Christian Reinhold Ott,Andreas Kaldun,Philipp Raith,Kristina Meyer,Martin Laux,Jörg Evers,Christoph H. Keitel,Chris H. Greene,Thomas Pfeifer,Thomas Pfeifer +9 more
TL;DR: A universal temporal-phase formalism is introduced, mapping the Fano asymmetry parameter q to a phase ϕ of the time-dependent dipole response function, which uses quantum-phase control to amplify extreme-ultraviolet light resonantly interacting with He atoms.
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
Arbitrated quantum-signature scheme
Guihua Zeng,Christoph H. Keitel +1 more
TL;DR: The general principle for a quantum-signature scheme is proposed and investigated and can guarantee the unconditional security of the algorithm, mostly due to the correlation of the GHZ triplet states and the use of quantum one-time pads.
