Photoassociation of long-range nD Rydberg molecules.
We observe long-range homonuclear diatomic nD Rydberg molecules photoassociated out of an ultracold gas of Rb87 atoms for 34≤n≤40. The measured ground-state binding energies of Rb87(nD+5S1/2) molecular states are larger than those of their Rb87(nS+5S1/2) counterparts, which shows the dependence of the molecular bond on the angular momentum of the Rydberg atom. We exhibit the transition of Rb87(...
متن کاملCreation of polar and nonpolar ultra-long-range rydberg molecules
We predict the existence of a ubiquitous class of long-range molecular Rydberg states, whose Born-Oppenheimer potential curves are oscillatory in nature. These oscillations reflect the nodal structure of the atomic Rydberg state wave functions. The temperature and density of atoms in a Bose-Einstein condensate are particularly favorable for the laser excitation of ultra-long-range vibrational b...
متن کاملUltra-long-range Rydberg molecules exposed to a magnetic field
We investigate the impact of an external magnetic field on ultra-long-range and ultracold Rydberg molecules. The Born–Oppenheimer potential surfaces are analysed and discussed for different values of the magnetic field strength. The magnetic field provides an angular confinement turning a rotational degree of freedom into a vibrational one. We explore the vibrational dynamics and observe a pron...
متن کاملLong-range interaction between polar Rydberg atoms
The most attractive and the most repulsive potential-energy curves for interaction between two Rydberg atoms in a broad superposition of internal angular momentum states are studied. The extreme Stark states have the largest dipole moments and provide the dominant contribution to the interaction which is then expressed as a long-range expansion involving the permanent multipole moments Qj of ea...
متن کاملAdiabatic rapid passage two-photon excitation of a Rydberg atom
We considered the two-photon adiabatic rapid passage excitation of a single atom from the ground to a Rydberg state. Three schemes were analyzed: both pump and Stokes fields chirped and pulsed, only the pump field chirped, and only the pump field pulsed and chirped while the Stokes field is continuous wave (CW). In all three cases high transfer efficiencies > 99% were achieved for the experimen...
