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…

Seeing topological edge and bulk currents in time-of-flight images
Alvaro Rubio-García, Chris N. Self, Juan Jose García-Ripoll +1
Here we provide a general methodology to directly measure the topological currents emerging in the optical lattice implementation of the Haldane model. Alongside the edge currents…

Topological bulk states and their currents
Chris N. Self, Alvaro Rubio-García, Juan Jose García-Ripoll +1
We provide evidence that, alongside topologically protected edge states, two-dimensional Chern insulators also support localised bulk states deep in their valance and conduction ba…
