Equivalence between vortices, twists and chiral gauge fields in Kitaev's honeycomb lattice model
Matthew D. Horner, Ashk Farjami, Jiannis K. Pachos
We demonstrate that gauge transformations and lattice deformations in Kitaev's honeycomb lattice model can have the same description in the continuum limit of the mo…
Geometric description of the Kitaev honeycomb lattice model
Ashk Farjami, Matthew D. Horner, Chris N. Self +2
It is widely accepted that topological superconductors can only have an effective interpretation in terms of curved geometry rather than gauge fields due to their charge neutrality…
Free fermion representation of the topological surface code
Ashk Farjami
The toric code is known to be equivalent to free fermions. This paper presents explicit local unitary transformations that map the toric and surface code --- the ope…
Free-fermion descriptions of parafermion chains and string-net models
Konstantinos Meichanetzidis, Christopher J. Turner, Ashk Farjami +2
Topological phases of matter remain a focus of interest due to their unique properties -- fractionalisation, ground state degeneracy, and exotic excitations. While some of these pr…
