Magical Mystery Tour of Electron Correlation

A Symposium in Honour of Jeppe Olsen on the Occasion of his 60th Birthday

About Jeppe Olsen

Throughout his whole career, Prof. Jeppe Olsen has worked on the hardest of all problems in quantum chemistry: the accurate treatment of electron correlation. Particularly important have been his many contributions to the development of multiconfigurational methods for static correlation, including efficient optimization techniques and advanced configuration-interaction methods. His pioneering contributions to time-dependent molecular properties established the framework and language of response theory in quantum chemistry, subsequently generalised and developed in many directions. He has contributed to the development and understanding of high-accuracy methods in quantum chemistry, including an explanation of divergence in Møller–Plesset theory. Jeppe Olsen is known to a whole generation of quantum chemists as an inspiring and influential teacher at European summer schools.

To honour Jeppe Olsen on the occasion of his 60th birthday (July 16 2016), 32 prominent scientists in the field of electronic-structure theory have been invited to present their recent work at the symposium, creating a broad picture of the state of the art. The meeting will take place at the Norwegian Academy of Science and Letters in Oslo.

19:30 Banquet 


Registration is free of charge but required if you would like to attend. Maximum capacity is 80 persons for the banquet and 105 for the conference.


Arrangment of the accommodation is left entirely to the participants (Hotel Gabelshus is the closest hotel - only 350 meters from the conference venue).


Det norske vitenskapsakademi (DNVA) is situated at Drammensveien 78. The location is close to tram line 13, see travel information here.

Eating Out

Lunch will be served (free of charge) at DNVA, but please indicate whether you would like lunch on Monday when you register. The banquet is on Wednesday evening (also sign up at registration), and it is open for accompanying persons. On Monday and Tuesday, the evening is "free", and here is a selection of restaurants to try, ranging from cheap yet excellent Asian cuisine to Michelin star awarded experiences.

Dining out in Norway may be expensive. Especially alcoholic drinks are pricey. The restaurants in the link above are chosen for their excellent quality/value balance.

Tipping is not compulsory, but if you are happy with the service and the food, you typically add/leave up to 10 % of the bill.


There will not be much time for sightseeing during the symposium, but in case you are staying longer you can take a look here.
