Symmetry of molecular Rydberg states revealed by XUV transient absorption spectroscopy [PDF]
Nature Communications, 2019 Transient absorption spectroscopy is used to identify the structural characteristics of the atoms and molecules. Here the authors used extreme ultraviolet transient absorption spectroscopy to identify the Rydberg state symmetry of aligned molecules.

Enhanced fragmentation of water dications upon high Rydberg states [PDF]
Nature CommunicationsThe ionization and fragmentation of water are fundamental processes across numerous scientific and technological fields, yet the relaxation pathways of water dications-particularly the rare D+ + O+ + D channel-remain poorly understood.

A detailed comparison of ΔSCF methods with the constraint-based orbital-optimized excited state method [PDF]
Communications ChemistryOrbital-optimized methods to variationally determine electronically excited states are becoming increasingly popular for overcoming some of the well-known shortcomings of linear-response theories. In this work we compare established ΔSCF methods with the

Vibrationally-dependent molecular dynamics in mutual neutralisation reactions of molecular oxygen ions [PDF]
Nature CommunicationsProduct distributions and dynamics of low-collision-energy mutual neutralisation reactions involving even simple molecular ions are largely unknown. Reactions which involve oxygen ions, e.g., $${{{\rm{O}}}}_{2}^{+}$$ O 2 + with O−, are expected to be ...

Long-Range Atom–Ion Rydberg Molecule: A Novel Molecular Binding Mechanism
Atoms, 2021 We present a novel binding mechanism where a neutral Rydberg atom and an atomic ion form a molecular bound state at a large internuclear distance. The binding mechanism is based on Stark shifts and level crossings that are induced in the Rydberg atom due

Exploring the vibrational series of pure trilobite Rydberg molecules
Nature Communications, 2023 In trilobite Rydberg molecules, an atom in the ground state is bound by electron-atom scattering to a Rydberg electron that is in a superposition of high angular momentum states.

Vibronic interactions in trilobite and butterfly Rydberg molecules
Physical Review Research, 2023 Ultralong-range Rydberg molecules provide an exciting testbed for molecular physics at exaggerated scales. In the so-called trilobite and butterfly Rydberg molecules, the Born-Oppenheimer approximation can fail due to strong nonadiabatic couplings ...

Enriching the Quantum Toolbox of Ultracold Molecules with Rydberg Atoms
PRX Quantum, 2022 We describe a quantum information architecture consisting of a hybrid array of optically trapped molecules and atoms. This design leverages the large transition dipole moments of Rydberg atoms to mediate fast, high-fidelity gates between qubits encoded ...

Observation of spin-orbit-dependent electron scattering using long-range Rydberg molecules
Physical Review Research, 2020 We present experimental evidence for spin-orbit interaction of an electron as it scatters from a neutral atom. The scattering process takes place within a Rb_{2} ultralong-range Rydberg molecule, consisting of a Rydberg atomic core, a Rydberg electron ...
