Mechanisms of cluster ionization in strong laser pulses
TLDR
In this paper, the main experimental observables for energy transfer to a cluster and the major theoretical approaches have been devised, and compared the cluster response to standard 780 nm light pulses with the response to 100 nm pulses, already obtained at a VUV free electron laser (FEL) source, and with 3 nm light which will be available from x-ray FEL sources.Abstract:
Femtosecond laser pulses have proven to provide valuable insight into the dynamics of microscopic systems by using pump–probe techniques. Applied to atomic clusters even a single pulse of varying pulse duration can reveal how and when energy from the laser pulse is transferred effectively to the cluster. We review the main experimental observables for energy transfer to a cluster and the major theoretical approaches which have been devised. Most importantly, we compare the cluster response to standard 780 nm light pulses with the response to 100 nm pulses, already obtained at a VUV free electron laser (FEL) source, and with 3 nm light which will be available from x-ray FEL sources.read more

Ultracold neutral plasmas
TL;DR: In this article, it was shown that strongly coupled plasmas, in which the electrical interaction energy between charged particles exceeds the average kinetic energy, reverse the traditional energy hierarchy underlying basic plasma concepts such as Debye screening and hydrodynamics.

Ultracold neutral plasmas
TL;DR: In this article, the average kinetic energy during equilibration and extremely fast recombination in ultracold neutral plasmas is studied. But the results are limited to the case where the average energy is proportional to the number of particles in the system.

Photoionisaton of pure and doped helium nanodroplets
TL;DR: In this paper, the photoionization (PI) spectroscopy of pure and doped He nanodroplets is discussed. But the focus of this paper is on the photo-physical properties of the He molecules and their relaxation dynamics following electronic excitation.

TL;DR: A novel method of directly calculating the force on N bodies that grows only as N log N is described, using a tree-structured hierarchical subdivision of space into cubic cells, each is recursively divided into eight subcells whenever more than one particle is found to occupy the same cell.

Free-Free Transitions Following Six-Photon Ionization of Xenon Atoms
TL;DR: In this article, the energy spectrum of electrons produced by multiphoton ionization of xenon atoms has been analyzed with a retarding potential technique, and it has been shown that the discrete absorption of photons above the six-photon ionization threshold was observable under specified conditions.
