Perturbative theory of ensemble-averaged atomic dynamics in fluctuating laser fields
Tejaswi Katravulapally, L. A. A. Nikolopoulos
We have developed a perturbative method to model the resonant ionization of atomic systems in fluctuating laser fields. The perturbative method is based on an expansion in terms of…
R-Matrix incorporating Time (RMT) method for H2+ in short and intense laser fields
Cathal Ó Broin, Lampros A. A. Nikolopoulos
In this work we develop an approach for a molecular hydrogen ion (H2+) in the Born-Oppenheimer approximation while exposed to intense short-pulse radiation. Our starting point is t…
A GPGPU based program to solve the TDSE in intense laser fields through the finite difference approach
Cathal Ó Broin, L. A. A Nikolopoulos
We present a General-purpose computing on graphics processing units (GPGPU) based computational program and framework for the electronic dynamics of atomic systems under intense la…
Coherent phase control in ionization of Magnesium by a bichromatic laser field of frequencies ωand 2ω
Gabriela Buica-Zloh, L. A. A. Nikolopoulos
We have investigated the coherent phase control on the (3p^{2}) autoionizing state (AIS) resonantly coupled with the ground state for Mg through a two- and a four-photon transition…
Time delay between photoemission from the 2p and 2s subshells of Neon
L. R. Moore, M. A. Lysaght, J. S. Parker +2
The R-Matrix incorporating Time (RMT) method is a new method for solving the time-dependent Schroedinger equation for multi-electron atomic systems exposed to intense short-pulse l…
An OpenCL implementation for the solution of TDSE on GPU and CPU architectures
Cathal Ó Broin, L. A. A. Nikolopoulos
Open Computing Language (OpenCL) is a parallel processing language that is ideally suited for running parallel algorithms on Graphical Processing Units (GPUs). In the present work…
