Quantum states of a two-electron atom trapped in a helical optical tube

We investigate the quantized states of a two-level Rb atom that is trapped by the optical dipole potential when the atom interacts with a helical optical tube light field. The analysis shows that the stationary states can be defined by a triplet of quantum numbers and the corresponding wave functions exhibit a twisted, spiral-like 3D spatial shape.
