Probing Atomic Majorana Fermions in Optical Lattices    [PDF]

Christina V. Kraus, Sebastian Diehl, Peter Zoller, Mikhail A. Baranov
We introduce a one-dimensional system of fermionic atoms in an optical lattice whose phase diagram includes topological states of different symmetry classes. These states can be identified by their zero-energy edge modes which are Majorana fermions. We propose several universal methods of detecting the Majorana edge states, based on their genuine features: zero-energy, localized character of the wave functions, and induced non-local fermionic correlations.
