A QMC-based framework tests the lattice-Bisognano-Wichmann ansatz for reconstructing entanglement Hamiltonians in 2D systems without Lorentz invariance or translational symmetry, finding good accuracy for ordinary boundaries.
Entanglement asymmetry for space-inversion symmetry of free fermions on honeycomb lattices exhibits nonanalytic dependence on energy imbalance and persists after a quench to the symmetric point due to flat bands in certain geometries.
