Parity effects and universal terms of $\mathcal{O}(1)$ in the entanglement near a boundary
In the presence of boundaries, the entanglement entropy in lattice models is known to exhibit oscillations with the (parity of the) length of the subsystem, which however decay to zero with increasing distance from the edge. We point out in this article that, when the subsystem starts at the bounda...
