We describe how optical contact lithography based on plasmon particle array masks allows generation of a large number of different subwavelength exposure patterns using a single mask. Within an exact point dipole model, we study the local response of

We have performed calculations of attosecond laser-atom interactions for laser intensities where interesting two- and three-photon effects become relevant. In particular, we examine the case of ``hole burning'' in the initial orbital. Hole burning is

The pulsed-field recombination scheme is used to recombine free electrons with ${\mathrm{Li}}^{+}$ ions to produce neutral Li atoms in a high Rydberg state $(n\ensuremath{\approx}180).$ The experimental conditions are similar to the conditions under

A novel method is presented to retrieve the average predissociation rate and the average rotational autoionization rate of a molecule by measuring the field ionization spectrum only. Both an intuitive picture and a quantitative description are derive

An optically excited Rydberg wavepacket can be generated by exciting the electron from a low-lying state to a coherent superposition of high-lying states with a short broadband optical pulse. A special kind of Rydberg wavepacket is generated in the c

A streak camera that operates in synchroscan mode has been developed with a spectral response throughout the infrared. A gas-phase sample of Rydberg atoms is used as a photocathode. This compact device possesses 5 ps time resolution and can be used w

We present a quantum theory for the interaction of a quantum target with a time dependent matter beam. When several pulses in the incident beam arrive with a period tau, transitions between levels with an energy difference h/tau can be enhanced. Unli

We present a novel approach to the preparation of neutral (anti-)matter. The scheme is based on recombination of a free electron and an ion, and can be considered as the inverse of pulsed field ionization. We have obtained promising results on rubidi

We report on the observation of stabilization of laser-excited rubidium Stark atoms above the classical ionization limit with the help of short (9 ns) unipolar electric-field pulses. Dipping the field down from 40 to 0 V/cm and back to 40 V/cm, 30 ns

In this Rapid Communication we report on the autoionization dynamics of the $5d7d$ doubly excited state in barium in a static electric field. The different experiments and theory show Stark beatings in the autoionization process. Also it appears that
