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 $N$-flavour Gross-Neveu model that manifestly respects the full $\mathsf{O}(2N)$ symmetry, preventing the appearance of any…
