Electrical conductivity for warm, dense aluminum plasmas and liquids.
The electrical conductivity of warm, dense aluminum plasmas and liquids is calculated using ab initio molecular dynamics and the Kubo-Greenwood formula. The density range extends from near solid toExpand

Watching dark solitons decay into vortex rings in a Bose-Einstein condensate.
We have created spatial dark solitons in two-component Bose-Einstein condensates in which the soliton exists in one of the condensate components and the soliton nodal plane is filled with the secondExpand

Evolution of ultracold neutral plasmas.
We present the first large-scale simulations of an ultracold neutral plasma, produced by photoionization of laser-cooled xenon atoms, from creation to initial expansion, using classicalExpand

Nonsequential two-photon double ionization of helium
We present accurate time-dependent ab initio calculations on fully differential and total integrated (generalized) cross sections for the nonsequential two-photon double ionization of helium atExpand

LETTER TO THE EDITOR: Triple-differential cross-sections for two-photon double ionization of He near threshold
Complete two-photon break-up of He near threshold has been investigated by solving the time-dependent closing-coupling equations on a numerical lattice. We have obtained good agreement for the totalExpand

Dark soliton states of Bose-Einstein condensates in anisotropic traps,
Dark soliton states of Bose-Einstein condensates in harmonic traps are studied both analytically and computationally by the direct solution of the Gross-Pitaevskii equation in three dimensions. TheExpand

Simulations of the optical properties of warm dense aluminum.
Using quantum molecular dynamics simulations, we show that the optical properties of aluminum change drastically along the nonmetal metal transition observed experimentally. As the density increasesExpand

Attosecond two-photon interferometry for doubly excited states of helium.
We show that the correlation dynamics in coherently excited doubly excited resonances of helium can be followed in real time by two-photon interferometry. This approach promises to map the evolutionExpand

Universal features in sequential and nonsequential two-photon double ionization of helium
We analyze two-photon double ionization of helium in both the nonsequential (({h_bar}/2{pi}){omega} I{sub 2}) regime. We show that the energy spacing {Delta}E=E{sub 1}-E{sub 2} between the twoExpand

Attosecond pump probe: exploring ultrafast electron motion inside an atom.
The attosecond pump probe, in close analogy to the standard femtosecond probing technique, has been proposed and theoretically demonstrated with its application to explore ultrafast electron motionsExpand
