PhD student Adenilson Felipe is currently an exchange student, working in the Hylleraas group under the supervision of Senior Researcher David Balcells. During his three-month stay, he will study the application of Generalized Additive Models (GAMs) to predict molecular properties of transition-metal complexes.

Dr. Benjamin Normann Frandsen joins the Hylleraas Centre in Oslo as an externally funded Researcher. Benjamin will explore atmospheric chemistry in extra-terrestrial atmospheres with a unique set of computational-chemistry methods, including density-functional theory, coupled-cluster models, and multi-reference methods.

Is it possible to observe positron-matter complexes before positron-electron annihilation? In a new paper published in The Journal of Chemical Physics by Hylleraas members Einar Aurbakken, Håkon Emil Kristiansen, Simen Kvaal, and Thomas Bondo Pedersen along with Antoine Camper from the Department of Physics at UiO, theoretical simulations of photopositron spectra predict that the answer is yes!

In close collaboration with Aparna Krishnan and Daniel Crawford at Virginia Tech and Ben Peyton at Michigan State University in the US, Håkon Emil Kristiansen and Thomas Bondo Pedersen published a paper on an orbital-level interpretation of correlated many-electron dynamics induced by ultrashort laser pulses. The paper is published in the Journal of Physical Chemistry A as part of the special issue “John F. Stanton Memorial Issue”.

In a project led by Jonas Mikkelsen and Frank Jensen at Aarhus University in Denmark, Simen Reine and Thomas Bondo Pedersen have published a new paper on the decomposition of molecular polarizabilities from coupled-cluster and MCSCF theory into atomic charge flow and induced dipole contributions. The results may support improved parameterizations of polarizable force fields for molecular dynamics simulations.

On April 25, roughly 100 school children aged 7 to 13 visited the Hylleraas Centre and the Department of Chemistry in Oslo to present the research projects they had worked on over the past 6 weeks. The event, “Hvorfor Det?” – a science fair for school kids – was organized by the parents’ board at Ila Skole in collaboration with the Hylleraas Centre.
