TU 3: Quantum many-body systems
[PIs: T. Luu, U.-G. Meißner, F. Neese]
Structure of TU "Quantum many-body systems"
The Principle Investigators of our TU are Thomas Luu, Frank Neese, and Ulf Meißner. These PIs will act as CASCADE spokespersons for any topic that falls within the umbrella of "Quantum many-body systems", whether it be physical or algorithmic in design. The TU itself will be in charge of the dissemination and referral of research and/or issues related to ``Quantum many-body systems" between external (non-CASCADE) and internal (within CASCADE) scientists. It also serves as a conduit between existing research areas within CASCADE to help facilitate and make more efficient internal communications.
We anticipate strong leadership roles to be taken by young investigators supported through CASCADE, as well as through senior postdocs.
The following subjects fall within this TU:
- Mean-field methods
- Coupled cluster theories (CCT)
- Density functional theory (DFT)
- Reduced scaling
- Stochastic methods
- Many-particle symmetries and group theory
- Green's functions methods
- Interface between classical and quantum methods
- Dynamics & reactions
Levels of interaction
We envision our TU containing three intertwined levels of interactions:
- External interactions. These interactions occur through conferences organized by CASCADE scientists or external scientists. Such interactions occur between CASCADE PIs and scientists not associated with CASCADE, as well as between students/postdocs of CASCADE with external scientists.
- Interactions between PIs. Here the interaction is not just between the TU PIs, but between all scientific collaborators of CASCADE. Interactions here involve organizing workshops, hackathons, and conferences, for example. Decisions on how best to disseminate research related to the TU amongst the research areas are done at this level.
- Interactions with students/postdocs. Our TU puts strong emphasis on student/postdoc initiative and career building. We provide the resources for strong interactions between students and postdocs with PIs within CASCADE, particularly the young investigators, and ask that students and postdocs play a major role (if not leading role) in organizing retreats and workshops. The goal here is the maximize their involvement and motivation and to develop their organizational skills, something that is of paramount importance for a cluster that involves such diverse research topics.
Contribution to CSCS
Many of the subject areas mentioned above are to a certain extent part of existing curricula that many of the PIs within CASCADE have taught (e.g. group theory), and so such courses can be easily adapted to the CSCS. New courses will have to be developed based on the requirements of CASCADE. For non-university PIs, block courses provide a convenient means for contributing to the CSCS, and the TU will provide support in such cases.
