Error estimates for extrapolations with matrix-product states
C. Hubig, J. Haegeman, U. Schollwöck
We introduce a new error measure for matrix-product states without requiring the relatively costly two-site density matrix renormalization group (2DMRG). This error measure is base…
Rigorous free fermion entanglement renormalization from wavelet theory
Jutho Haegeman, Brian Swingle, Michael Walter +3
We construct entanglement renormalization schemes which provably approximate the ground states of non-interacting fermion nearest-neighbor hopping Hamiltonians on the one-dimension…
Fermionic projected entangled-pair states and topological phases
Nick Bultinck, Dominic J. Williamson, Jutho Haegeman +1
We study fermionic matrix product operator algebras and identify the associated algebraic data. Using this algebraic data we construct fermionic tensor network states in two dimens…
Quasi-particle interactions in frustrated Heisenberg chains
Laurens Vanderstraeten, Jutho Haegeman, Frank Verstraete +1
Interactions between elementary excitations in quasi-one dimensional antiferromagnets are of experimental relevance and their quantitative theoretical treatment has been a theoreti…
The continuum limit of a tensor network: a path integral representation
Christoph Brockt, Jutho Haegeman, David Jennings +2
We argue that the natural way to generalise a tensor network variational class to a continuous quantum system is to use the Feynman path integral to implement a continuous tensor c…
