How machine learning helps us understand quantum matter
Annabelle Bohrdt · Photo: © LMUHow can we understand a material when its particles interact in ways that overwhelm conventional calculations?
At LMU’s Chair for Theoretical Solid State Physics, Annabelle Bohrdt and her group tackle this challenge by combining numerical methods, machine learning and close collaboration with quantum simulation experiments, exploring neural quantum states, patterns in quantum measurement data and models of strongly interacting particles.
Alongside Jan von Delft’s group, which develops numerical approaches to correlated quantum systems, they bring complementary perspectives to the study of quantum matter.
