Fermionic tensor network contraction for arbitrary geometries

Fermionic tensor network contraction for arbitrary geometries

We describe our implementation of fermionic tensor network contraction on arbitrary lattices within both a globally ordered and a locally ordered formalism. We provide a pedagogical description of these two conventions as implemented for the quimb library. Using hyperoptimized approximate contractio...
