Description
Infinite projected entangled-pair states (iPEPS) provide a state-of-the-art tool for studying strongly correlated systems in two dimensions directly in the thermodynamic limit. In the first lecture, I give a basic introduction to iPEPS, including standard contraction and optimization methods. The second lecture covers advanced iPEPS techniques and recent developments, including accelerated contractions, accurate evaluation of the energy variance with applications to the Shastry-Sutherland model, improved methods for computing excitation spectra based on the iPEPS excitation ansatz, and more.
