The resonant energy transfer between two close particles, also known as Förster resonance
in atomic or biological systems, is usually associated with dipole–dipole interaction. In …

An amplitude-modulated near-infrared laser pulse synchronized to a 14-GHz microwave
field is used to excite atoms to the vicinity of the ionization limit at specific phases of the …

We report microwave ionization experiments with Rydberg states of Na using several
microwave frequencies near 80 GHz. We observe substantial ionization of states as low as …

We study the quasistability of UV-pulse-train-excited H atoms in a strong infrared (IR) laser
as a function of the phase delay of the UV pulse train relative to the IR laser. The UV pulse …

The quasistability of highly exicited H and He atoms in a strong infrared (IR) field is studied
based on three-dimensional quantum calculations. The spectra of atoms that survive the IR …

Quantum mechanics, since its very beginning, has totally changed the way we understand
nature. The past hundred years have seen great successes in the application of quantum …

Laser excitation above the limit in the presence of a microwave field can lead to high lying
bound states if it occurs at the correct phase of the microwave field, and phase dependent …
