FIXNET

FIXNET is a 3-day in-person workshop addressing the growing need for advanced numerical methods to simulate strongly correlated quantum materials—systems central to high-temperature superconductivity, quantum magnetism, and topological phases.

We bring together experts and early-career researchers to consolidate recent advances in tensor networks applications in two dimensions.

Topics will include: 

• fixed-point methods in infinite PEPS and implicit differentiation for fixed points

• finite PEPS simulations with variational Monte Carlo and isometric tensor networks

• new approaches to excited state simulations and finite-temperature properties

• PEPS open-source software, GPU-accelerated implementations, scalable simulations with large symmetric (block-sparse) tensors on heterogeneous computer architectures. 

The workshop will be open and the introductory talks together with the tutorials will provide an opportunity for interested undergraduate and graduate students to learn about the state-of-the-art tensor network methods.
