Manipulating Topological Edge Spins in a One-Dimensional Optical Lattice

Manipulating Topological Edge Spins in a One-Dimensional Optical Lattice

We propose to observe and manipulate topological edge spins in a one-dimensional optical lattice based on currently available experimental platforms. Coupling the atomic spin states to a laser-induced periodic Zeeman field, the lattice system can be driven into a symmetry protected topological (SPT) phase, which belongs to the chiral unitary …
