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…
Fermionic tensor network methods
Quinten Mortier, Lukas Devos, Lander Burgelman +5
We show how fermionic statistics can be naturally incorporated in tensor networks on arbitrary graphs through the use of graded Hilbert spaces. This formalism allows to use tensor…
Finite-Entanglement Scaling of 2D Metals
Quinten Mortier, Ming-Hao Li, Jutho Haegeman +1
We extend the study of finite-entanglement scaling from one-dimensional gapless models to two-dimensional systems with a Fermi surface. In particular, we show that the entanglement…
Tensor Networks Can Resolve Fermi Surfaces
Quinten Mortier, Norbert Schuch, Frank Verstraete +1
We demonstrate that projected entangled-pair states (PEPS) are able to represent ground states of critical, fermionic systems exhibiting both 1d and 0d Fermi surfaces on a 2D latti…
