TT 40: Dual-Method Approaches to Quantum Many-Body Systems II

Dienstag, 13. März 2018, 10:00–13:00, H 3010

To make an impact on possible applications, theoretical approaches for correlated many-body systems must allow for studying more realistic models and lead to more accurate predictions as compared to what is achievable nowadays. This requires, on the one hand, the development of specialized tools which are mathematically and/or algorithmically demanding. On the other hand, an emergent promising approach to make significant progress beyond toy-model understanding of many-body physics is the combined use of two or more complementary methods. The demand for such type of approaches is growing. The two session of contributed talks will provide an overview of recent successes in such dual- (multi-)method approaches involving analytical as well as numerical tools, and will indicate prospects for future directions.
