SFB 1639:  NuMeriQS: Numerical Methods for Dynamics and Structure Formation in Quantum Systems

• Subject Area: Physics ; Chemistry ; Computer Science, Systems and Electrical Engineering ; Mathematics
• Term: since 2024
• Website: Homepage
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 511713970

The CRC initiative NuMeriQS brings together scientists from the fields of theoretical particle, nuclear, and condensed matter physics as well as theoretical chemistry on the one hand with mathematicians and computer scientists on the other hand in a truly interdisciplinary effort to improve our understanding of the structure and dynamics in quantum systems. NuMeriQS aims to leverage the sophisticated numerical methods developed separately in physics and chemistry by confronting them with the state of the art in numerical mathematics and computer science to tackle the central challenges all fields investigating complex quantum systems face. The initiative comes at a time where potentially transformative technologies become available, like the first exascale computing installations, or promise to become available, like digital quantum computers.
