Majorana Braiding in Realistic Nanowire Y-Junctions and Tuning Forks
Fenner Harper, Aakash Pushp, Rahul Roy
Majorana fermions are predicted to arise at the ends of nanowire devices which combine superconductivity, strong spin-orbit coupling and an external magnetic field. By manipulating…
Finite-wavevector Electromagnetic Response in Lattice Quantum Hall Systems
Fenner Harper, David Bauer, T. S. Jackson +1
In a quantum Hall system, the finite-wavevector Hall conductivity displays an intriguing dependence on the Hall viscosity, a coefficient that describes the non-dissipative response…
Chiral Flow in One-dimensional Floquet Topological Insulators
Xu Liu, Fenner Harper, Rahul Roy
We propose a bulk topological invariant for one-dimensional Floquet systems with chiral symmetry which quantifies the particle transport on each sublattice during the evolution. Th…
Interacting Floquet topological phases in three dimensions
Dominic Reiss, Fenner Harper, Rahul Roy
In two dimensions, interacting Floquet topological phases may arise even in the absence of any protecting symmetry, exhibiting chiral edge transport that is robust to local perturb…
