The Three-Legged Tree Tensor Networks with SU(2)- and molecular point group symmetry

Klaas Gunst, Frank Verstraete, Dimitri Van Neck

We extend the three-legged tree tensor network state (T3NS) [J. Chem. Theory Comput. 2018, 14, 2026-2033] by including spin and the real abelian point group symmetries. T3NS inters…
