Description

Leader of the group Scientific Computing: Daan Crommelin.

The world is full of uncertainties. Being able to assess those uncertainties and their impact on predictions is critical for many real-world problems. Our research group works to investigate and develop methods that contribute to a better understanding of hard-to-predict developments in vital areas such as climate, energy, and finance. It’s all about finding efficient mathematical solutions for complex problems and thereby increasing understanding. With the computational methods we develop, it is possible to quantify the range of potential outcomes of systems that are extremely difficult to predict, enabling better forecasting. Our work is targeted in particular at applications in energy systems, finance and climate science. We always aim to make the connection between fundamental research and practical application.

European consortium starts research on financial risk models

European consortium starts research on financial risk models

A European consortium of partners in academia and industry from the Netherlands, Italy and Spain has been granted 1,5 million euro for the Horizon 2020 research project WAKEUPCALL. The project, which  is coordinated by the Centrum Wiskunde & Informatica (CWI) in Amsterdam, combines academic expertise in financial mathematics with experience from partners in the finance and insurance industries.

Potential energy surfaces for molecular modelling

Potential energy surfaces represent the total energy of a system of nuclei and electrons as a function of the nuclear configuration. These surfaces (and property surfaces, such as the dipole moment) are key tools for quasi-classical trajectory calculations, molecular spectroscopy, quantum scattering and other applications in molecular science. In the talk I will first describe methods developed and used in collaboration with Joel Bowman (Emory University) to fit full-dimensional potential energy and dipole moment surfaces for small molecules and molecular reaction complexes, with up to about eight nuclei depending on the application. The methods take full account of permutational symmetry among like nuclei, and this required extensive use of computer algebra through the Magma system. I will follow up with discussion of areas for future work, including the treatment of electronic excited states, and of the need for high quality potential energy surfaces for studies of plasma-material interaction.
