Application of the Complex Kohn Variational Method to Attosecond Spectroscopy

August 6, 2018
Author(s)
Barry I. Schneider, Nicholas Douguet, Luca Argenti
The complex Kohn (CK) variational method is extended to compute light-driven electronic transitions between continuum wavefunctions in atomic and molecular systems. This development enables the study of multiphoton processes in the perturbative regime for

A Few Selected Contributions to electron and photon collisions with H_2+ and H_2

October 23, 2016
Author(s)
Barry I. Schneider, Lee A. Collins, klaus Bartschat, Xiaoxu Guan, Suxing Hu
We discuss a number of aspects regarding the physics of H_2+ nd H_2. This includes low-energy electron scattering processes and the interaction of both weak (perturbative) and strong (ultrafast/intense) electromagnetic radiation with those systems.

Time Propagation of Partial Differential Equations Using the Short Iterative Lanczos Method and Finite-Element Discrete Variable Representation: An Experiment Using the Intel Phi Coprocessors

July 15, 2016
Author(s)
Barry I. Schneider, klaus Bartschat, Xiaoxu Guan
The Short Iterative Lanczos (SIL) method has been combined with the Finite-Element Discrete Variable Representation (SIL-FEDVR) to yield a powerful approach to solving the time-dependent Schroedinger equation. It has been applied to the interaction of

The Protein Data Bank (PDB)

June 1, 2002

H M. Berman, T Battistuz, Talapady N. Bhat, W Bluhm, P E. Bourne, K Burkhardt, L Iype, Sanjay Jain, P Fagan, J Marvin, D Padilla, Veerasamy Ravichandran, Barry I. Schneider, N Thanki, H Weissig, J Westbrook, C Zardecki
The Protein Data Bank (PDB) is the single worldwide repository of structural data of biological macromolecules. This paper describes the goals of the PDB, the systems in place for data deposition and access, how to obtain further information, and near-term

Volume Visualization of Bose-Einstein Condensates

April 1, 2001
Author(s)
Peter M. Ketcham, D L. Feder, Charles W. Clark, Steven G. Satterfield, Terence J. Griffin, William L. George, Barry I. Schneider, W P. Reinhardt
Theoretical aspects of Bose-Einstein condensates are investigated by conducting computer simulations of their behavior. Scientific visualization techniques are employed in order to examine the large amount of data generated by simulation. Visualization of
