Automated tools for many-body theory
Organizers: P. Arthuis (TU Darmstadt, EMMI GSI), T. Duguet (CEA DPhN,
), F. A. Evangelista (Emory Univ., Atlanta, Georgia)
The main goals of the workshop are:
1. To introduce attendants to different approaches to computer-aided derivation techniques for many-body theory,
2. To exchange ideas regarding state-of-the-art automatic derivation methods between quantum chemists and nuclear physicists,
3. To discuss open problems in the field of automatic derivation, including the factorization of tensor contractions and identification of identical terms,
4. To identify ways to make current automatic derivation tools interoperable as a way to validate, benchmark, and expand the capabilities of current codes.
The first session (morning) is devoted to introductory presentations to inform the local research community on the state-of-the-art approaches developed to tackle the many-body problem.
The following sessions are focused on specific uses of automated derivation methods.
