Olivier Gauthé is an Associate Data Scientist at the Center for Computational Quantum Physics (CCQ) of the Flatiron Institute in New York City. Before moving to CCQ, he obtained a physics PhD in France at Toulouse III University and then joined EPFL in Lausanne, Switzerland as a postdoctoral researcher. He is working on numerical methods to study strongly correlated systems in condensed matter physics, with a focus on tensor network algorithms and 2D spin systems.
Session
Tensor network methods are a set of numerical algorithms designed to study strongly correlated systems in quantum physics. ITensors.jl is a high performance library providing easy access to them. As many physical models exhibit symmetries such as SU(2), enforcing them directly within the tensors leads to significant performance gains. In this talk, we introduce the core concepts of tensor networks, the basics of ITensor and expose its implementation of non-abelian symmetries.
