Error-correction properties of an interacting topological insulator
Amit Jamadagni, Hendrik Weimer
We analyze the phase diagram of a topological insulator model including antiferromagnetic interactions in the form of an extended Su-Schrieffer Heeger model. To this end, we employ…
An Operational Definition of Topological Order
Amit Jamadagni, Hendrik Weimer
The unrivaled robustness of topologically ordered states of matter against perturbations has immediate applications in quantum computing and quantum metrology, yet their very exist…
Topological Phase Transitions Induced by Varying Topology and Boundaries in the Toric Code
Amit Jamadagni, Arpan Bhattacharyya
One of the important characteristics of topological phases of matter is the topology of the underlying manifold on which they are defined. In this paper, we present the sensitivity…
Robustness of Topological Order in the Toric Code with Open Boundaries
Amit Jamadagni, Hendrik Weimer, Arpan Bhattacharyya
We analyze the robustness of topological order in the toric code in an open boundary setting in the presence of perturbations. The boundary conditions are introduced on a cylinder,…
