A logarithmically enhanced area law for the entanglement entropy in the random dimer model
AG Mathematische Physik

Referent: Ruth Schulte (LMU)
Raum: U1

We consider the random dimer model in one space dimension with Bernoulli disorder. For sufficiently small disorder, we show that the entanglement entropy exhibits 
(at least) a logarithmically enhanced area law if the Fermi energy coincides with a critical energy of the model where the localisation length diverges.
