CCP9 - Computational Electronic Structure of Condensed Matter

Workshop on solving the Bogoliubov-de Gennes and Gross-Pitaevskii equations for superconductors, superfluids and BEC

28-30 September 2007

Britannia Hotel, Manchester

Organisers

James F. Annett, Walter Temmerman and Balazs L. Gyorffy

Motivation

Pairing and condensation in degenerate Fermi and Bose systems remain at the centre of theoretical and experimental research in condensed matter physics. The equations referred to by the names of Bogoliubov-de Gennes and Gross-Pitaevskii provide a powerful, unifying conceptual framework for the study of quantum many-body phenomena associated with broken gauge symmetry, corresponding to the wide range of physical systems, such as superconductors, Bose-Einstein condensates of atoms and rotating nuclei. These are scientifc communities which do not meet as often as would be desirable from the point of view of rapid dissemination of new results and conceptual developments. The aim of the proposed workshop is to overcome such natural fragmentation and stimulate cross-fertilization of new ideas in these fields.
