Finite-size scaling on the torus with periodic projected entangled-pair states
Gleb Fedorovich, Lukas Devos, Jutho Haegeman +3
An efficient algorithm is constructed for contracting two-dimensional tensor networks under periodic boundary conditions. The central ingredient is a novel renormalization step tha…
Entanglement and the density matrix renormalisation group in the generalised Landau paradigm
Laurens Lootens, Clement Delcamp, Frank Verstraete
The fields of entanglement theory and tensor networks have recently emerged as central tools for characterising quantum phases of matter. In this article, we determine the entangle…
Interacting chiral fermions on the lattice with matrix product operator norms
Jutho Haegeman, Laurens Lootens, Quinten Mortier +3
We develop a Hamiltonian formalism for simulating interacting chiral fermions on the lattice while preserving unitarity and locality and without breaking the chiral symmetry. The f…
Local Jordan-Wigner transformations on the torus
Oliver O'Brien, Laurens Lootens, Frank Verstraete
We present a locality preserving unitary mapping from fermions to qubits on a 2D torus whilst accounting for the mapping of topological sectors. Extending the work of Shukla et al.…
