We investigate the fine and spin structure of ultralong-range Rydberg molecules exposed to a homogeneous magnetic field. Each molecule consists of a $^{87}$Rb Rydberg atom whose outer electron interacts via spin-dependent $s$- and p-wave scattering with a polarizable $^{87}$Rb ground state atom. Our model includes also the hyperfine structure of the ground state atom as well as spin-orbit couplings of the Rydberg and ground state atom. We focus on $d$-Rydberg states and principal quantum…

Precision Spectroscopy of Negative-Ion Resonances in Ultralong-Range Rydberg Molecules.

It is demonstrated that a single ultracold atom bound inside a Rydberg orbit forming an ultralong-range Ryd Berg molecule provides an atomic-scale system that is highly sensitive to electron-neutral scattering and thus allows for detailed insights into the underlying near-threshold anion states.

Excitation of Rydberg Molecules in Ultracold Quantum Gases

Recent experiments in our group on the excitation of Rydberg molecules in ultracold quantum gases have been reviewed. Quantum gases are a well‐suited environment to excite Rydberg molecules, due to

Hamiltonian for the inclusion of spin effects in long-range Rydberg molecules

The interaction between a Rydberg electron and a neutral atom situated inside its extended orbit is described via contact interactions for each atom-electron scattering channel. In ultracold

Observation of ultralong-range Rydberg molecules

The spectra of the vibrational ground state and of the first excited state of the Rydberg molecule, the rubidium dimer Rb(5s)–Rb(ns), agree well with simple model predictions and allow us to extract the s-wave scattering length for scattering between the R Sydberg electron and the ground-state atom, Rb (5s), in the low-energy regime.

From molecular spectra to a density shift in dense Rydberg gases

Those Rydberg molecules created by photoassociation for the spherically symmetric S-states are investigated, and a step by step increase of the principal quantum number up to n=111 enables us to go beyond the previously observed dimer and trimer states up to a molecule, where four ground state atoms are bound by one Ryd Berg atom.

Probing an Electron Scattering Resonance using Rydberg Molecules within a Dense and Ultracold Gas.

A simple microscopic model for the spectroscopic line shape is presented by treating the atoms overlapped with the Rydberg orbit as zero-velocity, uncorrelated, pointlike particles, with binding energies associated with their ion-neutral separation, and good agreement is found.

Rydberg Molecule-Induced Remote Spin Flips.

High resolution photoassociation spectroscopy of rubidium ultralong-range Rydberg molecules in the vicinity of the 25P state shows that the emerging mixed singlet-triplet potentials contain contributions from both hyperfine states, and can be used to induce remote spin flips in the perturber atom upon excitation of a Ryd Berg molecule.
