Hybrid basis and multi-center grid method for strong-field processes
Kyle A. Hamer, Heman Gharibnejad, Luca Argenti +1
We present a time-dependent framework that combines a hybrid Gaussian-FEDVR basis with a multicenter grid to simulate strong-field and attosecond dynamics in atoms and molecules. T…
ASTRA, A Transition Density Matrix Approach to the Interaction of Attosecond Radiation with Atoms and Molecules
Juan M Randazzo, Carlos Marante, Siddhartha Chattopadhyay +4
A new formalism and computer code, ASTRA (AttoSecond TRAnsitions), has been developed to treat the interactions of short, intense radiation with molecules. The formalism makes exte…
ITVOLT: An Iterative Solver for the Time-Dependent Schrödinger Equation
Ryan Schneider, Heman Gharibnejad, Barry I. Schneider
We present a novel approach for solving the time-dependent Schrödinger equation (TDSE). The method we propose converts the TDSE to an equivalent Volterra integral equation; introdu…
A Multi-Center Quadrature Scheme for the Molecular Continuum
Heman Gharibnejad, Nicolas Douguet, Jeppe Olsen +2
A common way to evaluate electronic integrals for polyatomic molecules is to use Becke's partitioning scheme [J. Chem. Phys.88, 2547 (1988)] in conjunction with overlapping grids c…
Comparison of Numerical Approaches to the Time-Dependent Schrödinger Solutions in One Dimension
Heman Gharibnejad, Barry I. Schneider, Mark Leadingham +1
We examine the performance of various time propagation schemes using a one-dimensional model of the hydrogen atom. In this model the exact Coulomb potential is replaced by a soft-c…
Dark forces and atomic electric dipole moments
Heman Gharibnejad, Andrei Derevianko
Postulating the existence of a fnite-mass mediator of T,P-odd coupling between atomic electrons and nucleons we consider its effect on permanent electric dipole moment (EDM) of dia…
