Renormalization group flows for Wilson-Hubbard matter and the topological Hamiltonian
E. Tirrito, M. Rizzi, G. Sierra +2
Understanding the robustness of topological phases of matter in the presence of interactions poses a difficult challenge in modern condensed matter, showing interesting connections…
Characterizing the quantum field theory vacuum using temporal Matrix Product states
Emanuele Tirrito, Neil J. Robinson, Maciej Lewenstein +2
In this paper we construct the continuous Matrix Product State (MPS) representation of the vacuum of the field theory corresponding to the continuous limit of an Ising model. We do…
Gross-Neveu-Wilson model and correlated symmetry-protected topological phases
A. Bermudez, E. Tirrito, M. Rizzi +2
We show that a Wilson-type discretization of the Gross-Neveu model, a fermionic N-flavor quantum field theory displaying asymptotic freedom and chiral symmetry breaking, can serve…
