Topological order in perturbed toric code models — •Amit Jamadagni Gangapuram and Hendrik Weimer — Institut für Theoretische Physik, Leibniz Universität Hannover, Hannover, Germany.

We present a few signatures to detect topological order using concepts from quantum information. Based on the toric code model, we construct various closed and open quantum systems that encode a possible topological phase transition. We compare various approaches to topological order by their ability to successfully detect topological phase transitions within these models.
