A many-body interpretation of Majorana bound states, and conditions for their localisation
T. E. O'Brien, A. R. Wright
We derive a condition for the existence of completely or exponentially localised Majorana bound states (with the potential for non-Abelian statistics) in a generic many-body system…
Zeeman field induced topological phase transitions in triplet superconductors
Timo Hyart, Anthony R. Wright, Bernd Rosenow
We develop a general Ginzburg-Landau theory which describes the effect of a Zeeman field on the superconducting order parameter in triplet superconductors. Starting from Ginzburg-L…
Many-particle Majorana bound states: derivation and signatures in superconducting double quantum dots
Thomas E. O'Brien, Anthony R. Wright, Menno Veldhorst
We consider two interacting quantum dots coupled by standard superconductors. We derive an effective Hamiltonian, and show that over a wide parameter range a degenerate ground stat…
Signatures of the Berry curvature in the frequency dependent interlayer magnetoresistance in tilted magnetic fields
Anthony R. Wright, Ross H. McKenzie
We show that in a layered metal, the angle dependent, finite frequency, interlayer magnetoresistance is altered due to the presence of a non-zero Berry curvature at the Fermi surfa…
Localized Many-Particle Majorana Modes with Vanishing Time-Reversal Symmetry Breaking in Double Quantum Dots
Anthony R. Wright, Menno Veldhorst
We introduce the concept of spinful many-particle Majorana modes with local odd operator products, thereby preserving their local statistics. We consider a superconductor-double-qu…
Realising Haldane's vision for a Chern insulator in buckled lattices
Anthony R. Wright
The Chern insulator displays a quantum Hall effect with no net magnetic field. Proposed by Haldane over 20 years ago, it laid the foundation for the fields of topological order, un…
