Ultralong-range Cs-RbCs Rydberg molecules: Nonadiabaticity of dipole moments Mellado Alcedo, David Guttridge, Alexander Cornish, Simon L. Sadeghpour, H. R. González Férez, María Rosario We consider ultralong-range polyatomic Rydberg molecules formed by combining a Rydberg cesium atom and a ground-state RbCs molecule. We explore the regime where the charge-dipole interaction due to the Rydberg electron with the diatomic polar molecule couples the quantum defect Rydberg states Cs(ns) to the nearest degenerate hydrogenic manifold. We consider polyatomic Rydberg molecules in states which are amenable to production in optical tweezers and study the influence of nonadiabatic coupling on the likelihood of their formation. The decay rates of the vibrational states reflect the interference signature of wave function spread in different coupled potential wells. 2024-07-31T11:14:18Z 2024-07-31T11:14:18Z 2024-07-15 journal article Phys.
