Topological edge states with ultracold atoms carrying orbital angular momentum in a diamond chain
Topological edge states with ultracold atoms carrying orbital angular momentum in a diamond chain
We study the single-particle properties of a system formed by ultracold atoms loaded into the manifold of $l=1$ Orbital Angular Momentum (OAM) states of an optical lattice with a diamond chain geometry. Through a series of successive basis rotations, we show that the OAM degree of freedom induces phases in …
