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…
Hawking radiation on the lattice from Floquet and local Hamiltonian quench dynamics
Daan Maertens, Nick Bultinck, Karel Van Acoleyen
We construct two free fermion lattice models exhibiting Hawking pair creation. Specifically, we consider the simplest case of a d=1+1 massless Dirac fermion, for which the Hawking…
Mapping topological to conformal field theories through strange correlators
Matthias Bal, Dominic J. Williamson, Robijn Vanhove +3
We extend the concept of strange correlators, defined for symmetry-protected phases in [You et al., Phys. Rev. Lett. 112, 247202 (2014)], to topological phases of matter by taking…
Symmetry-enriched topological order in tensor networks: Defects, gauging and anyon condensation
Dominic J. Williamson, Nick Bultinck, Frank Verstraete
We study symmetry-enriched topological order in two-dimensional tensor network states by using graded matrix product operator algebras to represent symmetry-induced domain walls. A…
Fermionic Matrix Product Operators and Topological Phases of Matter
Dominic J. Williamson, Nick Bultinck, Jutho Haegeman +1
We introduce the concept of fermionic matrix product operators, and show that they provide a natural representation of fermionic fusion tensor categories. This allows for the class…
The entanglement of distillation for gauge theories
Karel Van Acoleyen, Nick Bultinck, Jutho Haegeman +3
We study the entanglement structure of lattice gauge theories from the local operational point of view, and, similar to Soni and Trivedi (arXiv:1510.07455), we show that the usual…
Matrix product operators for symmetry-protected topological phases: Gauging and edge theories
Dominic J. Williamson, Nick Bultinck, Michael Mariën +3
Projected entangled pair states (PEPS) provide a natural ansatz for the ground states of gapped, local Hamiltonians in which global characteristics of a quantum state are encoded i…
Characterizing Topological Order with Matrix Product Operators
Mehmet Burak Şahinoğlu, Dominic Williamson, Nick Bultinck +4
One of the most striking features of quantum phases that exhibit topological order is the presence of long range entanglement that cannot be detected by any local order parameter.…
