Lattice regularisation and entanglement structure of the Gross-Neveu model
Gertian Roose, Nick Bultinck, Laurens Vanderstraeten +3
We construct a Hamiltonian lattice regularisation of the -flavour Gross-Neveu model that manifestly respects the full symmetry, preventing the appearance of any…
Entanglement compression in scale space: from the multiscale entanglement renormalization ansatz to matrix product operators
Karel Van Acoleyen, Andrew Hallam, Matthias Bal +3
The multiscale entanglement renormalization ansatz (MERA) provides a constructive algorithm for realizing wavefunctions that are inherently scale invariant. Unlike conformally inva…
Simulating Lattice Gauge Theories within Quantum Technologies
M. C. Bañuls, R. Blatt, J. Catani +17
Lattice gauge theories, which originated from particle physics in the context of Quantum Chromodynamics (QCD), provide an important intellectual stimulus to further develop quantum…
A scaling hypothesis for matrix product states
Bram Vanhecke, Jutho Haegeman, Karel Van Acoleyen +2
We revisit the question of describing critical spin systems and field theories using matrix product states, and formulate a scaling hypothesis in terms of operators, eigenvalues of…
Consistent long distance modification of gravity from inverse powers of the curvature
Ignacio Navarro, Karel Van Acoleyen
In this paper we study long distance modifications of gravity obtained by considering actions that are singular in the limit of vanishing curvature. In particular, we showed in a p…
