Logarithmic lower bounds for the entanglement entropy of droplet states for the XXZ model on the ring

Abstract: We study the free XXZ quantum spin model defined on a ring of size L and show that the bipartite entanglement entropy of eigenstates belonging to the first energy band above the vacuum ground state satisfy a logarithmically corrected area law. This is joint work with Ruth Schulte (LMU).
