Abstract
We analytically evaluate the entanglement spectra of the superconductivity states in graphene, primarily focusing on the s-wave and chiral dx2-y2 + idxy superconductivity states. We demonstrate that the topology of the entanglement Hamiltonian can differ from that of the subsystem Hamiltonian. In particular, the topological properties of the entanglement Hamiltonian of the chiral dx2-y2 + idxy superconductivity state obtained by tracing out one spin direction clearly differ from those…
