Our ties to the Centre for Advanced Study (CAS) at the Norwegian Academy of Science Letters are strong, as emphasized in an interview with the Hylleraas Director Trygve Helgaker for the CAS Newsletter. The interviewed was prompted by Helgaker's return to CAS as a fellow of the CAS Project Attosecond Quantum Dynamics Beyond the Born–Oppenheimer Approximation led by Hylleraas members Thomas Bondo Pedersen and Simen Kvaal in the coming 2020/2021 academic year, only a three years after Helgaker had led the CAS Project Molecules in Extreme Environments during the 2017/2018 academic year. Both CAS projects concern tha interaction of molecules with electromagnetic fields — laser pulses in the attosecond project and ultrastrong magnetic fields in the project on extreme enviroments. Most fellows of the 2017/2018 CAS Project visited the Hylleraas Centre for one week in 2019.
Remarkably, two young researchers at the Hylleraas Centre have also been successful in securing projects at CAS. André Laestadius led the YoungCAS Workshop Do Electron Current Densities Determine All There Is to Know? in 2018, while Erik Tellgren is the leader of the 2020/2021 YoungCAS Project Global Optimisation in Electronic Energy Landscapes: Finding a Needle in a Haystack, postponed by the pandemic.
In an interview for the CAS Newsletter, Hylleraas member Andy Teale, assistant professor at the University of Nottingham and adjunct professor at the University of Oslo, was celebrated as the first scholar to participate in both a standard and young CAS projects, having been a fellow of both the CAS Project of Helgaker and the YoungCAS Project of Laestadius. We would also like to draw the attention to an interview in the CAS Newsletter with Profesor Peter Schwerdtfeger, a fellow of the CAS Project Molecules in Extreme Environments.
