Robustness of the flux-free sector of the Kitaev honeycomb against environment
Alexander Sattler, Maria Daghofer
The Kitaev honeycomb model (KHM) consists of spin- particles on a honeycomb lattice with direction-dependent Ising-like interactions. It can alternatively be described in term…

Robustness of topological edge states in alternating spin chains against environment
Alexander Sattler, Maria Daghofer
Both the Haldane spin- chain and dimerized chains of spin- exhibit topologically protected edge states that are robust against specific perturbations. Recently, such spin c…

Promising regimes for the observation of topological degeneracy in spin chains
Alexander Sattler, Maria Daghofer
Both the Haldane spin chain and a topologically dimerized chain feature topologically protected edge states that are expected to be robust against some kind of noise. To elucidate…
