Eigenvector continuation method in nuclear structure and reaction theory



T. Duguet (CEA DPhN, ), A. Ekström (Chalmers Univ, Goteborg), R. J. Furnstahl (The Ohio State Univ.), S. König (North Carolina State Univ.), D. Lee (FRIB, MSU)


The main goals of the workshop are:

1. to review the eigenvector continuation method and its various uses in nuclear structure and reaction theory,
2. to discuss further potential applications, extensions and alternatives.

The meeting takes place over 4 days. The first day is devoted to introductory presentations that have the aim of informing the local research community on the state-of the-art approaches developed to tackle the many-body problem. The following days will be focused on specific uses of the eigenvector continuation (EVC) method along with other extrapolation techniques.
