Title:
Advances in simulating 2D strongly correlated systems with iPEPS
Speaker:
Abstract:
In this talk I report on recent progress with infinite projected-entangled pair states (iPEPS) - a two-dimensional tensor network ansatz for 2D ground states in the thermodynamic limit. Thanks to several advances on the methods side, including more accurate and efficient optimization and contraction algorithms, making use of symmetries, and improved extrapolation techniques, iPEPS has become a very powerful tool for the study of 2D strongly correlated systems. I will give an overview of recent developments and simulation results for challenging problems, including the 2D Hubbard model and frustrated spin systems.
