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…
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,…
A simple tensor network algorithm for two-dimensional steady states
Augustine Kshetrimayum, Hendrik Weimer, Roman Orus
Understanding dissipation in 2D quantum many-body systems is a remarkably difficult open challenge. Here we show how numerical simulations for this problem are possible by means of…
