Hubbard model on the Bethe lattice via variational uniform tree states: Metal-insulator transition and a Fermi liquid
We numerically solve the Hubbard model on the Bethe lattice with finite coordination number z=3, and determine its zero-temperature phase diagram. For this purpose, we introduce and develop the “variational uniform tree state” (VUTS) algorithm, a tensor-network algorithm which generalizes the variat...
