Numerical simulations of the triangular Majorana-Hubbard ladder reveal multiple symmetry-protected topological phases identified through entanglement spectrum degeneracies and adiabatic connections.
As such, we should expect the generalized mean-field to have an energy density bounded from above by the simplified version
