Ultralong-Range Rb-KRb Rydberg Molecules: Selected Aspects of Electronic Structure, Orientation and Alignment

Abstract

We investigate the structure and features of an ultralong-range triatomic Rydberg molecule formed by a Rb Rydberg atom and a KRb diatomic molecule. In our numerical description, we perform a realistic treatment of the internal rotational motion of the diatomic molecule, and take into account the Rb($n,l\ge 3$) Rydberg degenerate manifold and the energetically closest neighboring levels with principal quantum numbers $n^{\prime }>n$ and orbital quantum number $l\le 2$. We focus here on the adiabatic electronic potentials evolving from the Rb($n,l\ge 3$) and Rb($n=26,l=2$) manifolds. The directional properties of the KRb diatomic molecule within the Rb-KRb triatomic Rydberg molecule are also analyzed in detail.
