Topological crystals and soliton lattices in a Gross-Neveu model with Hilbert-space fragmentation

Sergio Cerezo-Roquebrún, Simon Hands, Alejandro Bermudez

We explore the finite-density phase diagram of the single-flavour Gross-Neveu-Wilson (GNW) model using matrix product state (MPS) simulations. At zero temperature and along the sym…
