Continuum limit of gauged tensor network states
Gertian Roose, Erez Zohar
It is well known that all physically relevant states of gauge theories lie in the sectors of the Hilbert space which satisfy the Gauss law. On the lattice, the manifeslty gauge inv…
T-duality and bosonization as examples of continuum gauging and disentangling
Gertian Roose, Erez Zohar
Dualities and duality transformations form a well established methodology in various aspects of quantum many body physics and quantum field theories, allowing one to exploit equiva…
Gauging a superposition of fermionic Gaussian projected entangled pair states to get lattice gauge theory eigenstates
Gertian Roose, Erez Zohar
Gauged fermionic projected entangled pair states (GFPEPS) and their Gaussian counterpart (GGFPEPS) are a novel type of lattice gauge theory Ansatz state that combine ideas from the…
Gauged Gaussian PEPS -- A High Dimensional Tensor Network Formulation for Lattice Gauge Theories
Ariel Kelman, Umberto Borla, Itay Gomelski +4
Gauge theories form the basis of our understanding of modern physics - ranging from the description of quarks and gluons to effective models in condensed matter physics. In the non…
The Chiral Gross-Neveu model on the lattice via a Landau-forbidden phase transition
Gertian Roose, Jutho Haegeman, Karel Van Acoleyen +2
We study the phase diagram of the -dimensional Gross-Neveu model with both and interaction terms on a spatial lattice. The continuous…
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…
Anomalous domain wall condensation in a modified Ising chain
Gertian Roose, Laurens Vanderstraeten, Jutho Haegeman +1
We construct a one-dimensional local spin Hamiltonian with an intrinsically non-local, and therefore anomalous, global symmetry. The model is closely related to the…
