Lower Bound to the Entanglement Entropy of the XXZ Spin Ring
Christoph Fischbacher, Ruth Schulte
We study the free XXZ quantum spin model defined on a ring of size and show that the bipartite entanglement entropy of eigenstates belonging to the first energy band above the…

Stability of the enhanced area law of the entanglement entropy
Peter Müller, Ruth Schulte
We consider a multi-dimensional continuum Schrödinger operator which is given by a perturbation of the negative Laplacian by a compactly supported potential. We establish both an u…
