Majorana modes and $p$-wave superfluids for fermionic atoms in optical lattices

Quantum Gases 2014-07-29 v1

Abstract

We present a simple approach to create a strong pp-wave interaction for fermions in an optical lattice. The crucial step is that the combination of a lattice setup with different orbital states and ss-wave interactions can give rise to a strong induced pp-wave pairing. We identify different topological phases and demonstrate that the setup offers a natural way to explore the transition from Kitaev's Majorana wires to two-dimensional pp-wave superfluids. We demonstrate how this design can induce Majorana modes at edge dislocations in the optical lattice, and we provide an experimentally feasible protocol for the observation of the non-Abelian statistics.
