Novel tensor network methods for strongly correlated quantum systems

In this Focus Group, Hans Fischer Senior Fellow Prof. Örs Legeza (Wigner Research Centre for Physics) works with his host Prof. Gero Friesecke (Analysis, TUM) and doctoral student Elizabeth Adomako Boamah.

The main research interests focus on the development of novel tensor network state (TNS) methods and their application to strongly correlated quantum many-body systems to simulate and study magnetic properties in solid states, exotic quantum phases, complex molecular clusters, ultracold atomic systems or nuclear structures. For the method development we combine established methods for simple networks (MPS, MERA, tensor trees) with concepts from quantum information theory and computational mathematics to push the current frontier of moderate system size to much larger and more complex systems.
