The objective of this workshop is to bring together researchers working in the application of quantum theory to cosmology, and those working on foundational aspects of quantum theory. These two fields have a very important intersection, exemplified by the fact that many approaches that have been developed to deal with the conceptual difficulties, particularly with the so called “measurement problem” in quantum  mechanics, become almost untenable in their application to cosmology. On the other hand, the views about the nature of quantum theory that are most popular amongst researchers working in modern cosmology are being critically scrutinized within the foundational community.

This situation indicates that there is a very large potential for fruitful exchange and cross-fertilization of ideas among these two communities, which have not in the past had a strong  interaction. The workshop will be organized with emphasis on promoting interaction and discussion. There will be a small number of formal presentations and a series of long discussion sessions with specific focus topics.

 Registration deadline: September 22
