Faster Methods for Contracting Infinite 2D Tensor Networks
M. T. Fishman, L. Vanderstraeten, V. Zauner-Stauber +2
We revisit the corner transfer matrix renormalization group (CTMRG) method of Nishino and Okunishi for contracting two-dimensional (2D) tensor networks and demonstrate that its per…
Spinon confinement in a quasi one dimensional anisotropic Heisenberg magnet
A. K. Bera, B. Lake, F. H. L. Essler +6
Confinement is a process by which particles with fractional quantum numbers bind together to form quasiparticles with integer quantum numbers. The constituent particles are confine…
Bridging Perturbative Expansions with Tensor Networks
Laurens Vanderstraeten, Michaël Mariën, Jutho Haegeman +3
We demonstrate that perturbative expansions for quantum many-body systems can be rephrased in terms of tensor networks, thereby providing a natural framework for interpolating pert…
Variational optimization algorithms for uniform matrix product states
V. Zauner-Stauber, L. Vanderstraeten, M. T. Fishman +2
We combine the Density Matrix Renormalization Group (DMRG) with Matrix Product State tangent space concepts to construct a variational algorithm for finding ground states of one di…
