Multiple absorption of laser photons by atoms
TL;DR: In this paper, the Schrodinger equation for an atom in an electromagnetic field is solved with sufficient accuracy to obtain probabilities for multiple absorption of photons from a monochromatic laser beam of arbitrary intensity or frequency.

Topics on Multiphoton Processes in Atoms
TL;DR: In this article, the theory of multiphoton processes can be developed in a semiclassical or fully quantum mechanical formalism, and the momentum translation approximation (MTA) is a rearrangement of perturbation theory.

Gauge transformations and quantum mechanics I. Gauge invariant interpretation of quantum mechanics
Kuo-Ho Yang,Kuo-Ho Yang +1 more
TL;DR: In this article, it was shown that probability amplitudes and transition matrix elements are gauge-invariant for a nonrelativistic spinless, spinless charged particle.
Journal ArticleDOI
Anomalous Collision-Free Multiple Ionization of Atoms with Intense Picosecond Ultraviolet Radiation
TL;DR: In this paper, a mode of interaction involving radiative coupling to a collective motion of an atomic shell is proposed to describe the anomalously strong coupling in collisionless multiphoton absorption.
Journal ArticleDOI
Collision-free multiple photon ionization of atoms and molecules at 193 nm.
TL;DR: The experimental evidence points to a coherent atomic motion involving several electrons, possibly an entire shell, as the main physical mechanism enabling the scale of energy transfers seen, a consideration that fundamentally distinguishes the nonlinear interaction of a multielectron atom from that of a single-electron system.
