Thomas Bondo Pedersen presented recent research on making chemical sense of coupled-cluster dynamics at the workshop “New Developments in Coupled-Cluster Theory” in Telluride, Colorado, USA.

This summer Professor of theoretical Chemistry, Ludwik Adamowicz, takes a break from the hot summer in Arizona to work with Professor Thomas Bondo Pedersen and Professor Simen Kvaal at Hylleraas Centre at University of Oslo.

In a new paper, it is demonstrated that superpositions of Gaussian wave packets can be propagated in a numerically stable manner, providing highly accurate results for the quantum dynamics of molecular systems driven by extreme laser pulses.

This spring Professor Ludwik Adamowicz will work with Professor Thomas Bondo Pedersen and Professor Simen Kvaal during his stay.

Hylleraas members Oliver Bohle, Mihaly Csirik, Trygve Helgaker, Simen Kvaal, Thomas Bondo Pedersen, Simon Elias Schrader and Erik Tellgren presented their recent work at the at the workshop “Extensions and Foundations of Density-Functional Theory” at Oslo Metropolitan University. 

The adiabatic Born-Oppenheimer approximation permeates our fundamental understanding of chemistry but breaks down when molecules interact with attosecond laser pulses. In his seminar at the Department of Chemistry at Aarhus University, Thomas Bondo Pedersen outlined how researchers at the Hylleraas Centre are tackling this challenge.

Special attention was paid to the major computational and theoretical challenges associated with laser-induced ionization processes and high-harmonic generation.
