Electrical conductivity for warm, dense aluminum plasmas and liquids.
- M. Desjarlais, J. D. Kress, L. Collins
- Materials Science, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 1 August 2002
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 to… Expand
Watching dark solitons decay into vortex rings in a Bose-Einstein condensate.
- B. P. Anderson, P. Haljan, +4 authors E. Cornell
- Physics, Medicine
- Physical review letters
- 22 December 2000
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 second… Expand
Evolution of ultracold neutral plasmas.
- S. Mazevet, L. Collins, J. D. Kress
- Physics, Medicine
- Physical review letters
- 17 November 2001
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 classical… Expand
Nonsequential two-photon double ionization of helium
- J. Feist, S. Nagele, +4 authors J. Burgdorfer
- Physics
- 4 March 2008
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 at… Expand
LETTER TO THE EDITOR: Triple-differential cross-sections for two-photon double ionization of He near threshold
- S. Hu, J. Colgan, L. Collins
- Physics
- 14 January 2005
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 total… Expand
Dark soliton states of Bose-Einstein condensates in anisotropic traps,
- D. Feder, M. Pindzola, L. Collins, B. Schneider, C. W. Clark
- Physics
- 26 April 2000
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. The… Expand
Simulations of the optical properties of warm dense aluminum.
- S. Mazevet, M. Desjarlais, L. Collins, J. D. Kress, N. H. Magee
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 2005
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 increases… Expand
Attosecond two-photon interferometry for doubly excited states of helium.
- J. Feist, S. Nagele, C. Ticknor, B. Schneider, L. Collins, J. Burgdörfer
- Physics, Medicine
- Physical review letters
- 19 April 2011
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 evolution… Expand
Universal features in sequential and nonsequential two-photon double ionization of helium

- Physics
- 8 February 2011
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 two… Expand
Attosecond pump probe: exploring ultrafast electron motion inside an atom.

- 24 February 2006
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 motions… Expand
