Vibronic quantum dynamics of ultralong-range high- Rydberg molecules
Felix Giering, Rohan Srikumar, Peter Schmelcher
We investigate the non-adiabatic quantum dynamics of ultralong-range Rydberg molecules using a vibronically coupled two-channel treatment. The two-channels are composed of coupled…
Observation of spin singlet butterfly Rydberg molecules in an ultracold atomic Rb gas
Markus Exner, Rohan Srikumar, Richard Blättner +4
We report the observation of spin-singlet ultra-long range Rydberg butterfly molecules consisting of a ground-state atom bound to a Rydberg atom by -wave scattering of Rb…
Vibrationally highly excited trilobite molecules stabilized by non-adiabatic coupling
Rohan Srikumar, Markus Exner, Richard Blättner +3
We report on the observation of highly excited ( vibrational states of a trilobite ultralong-range Rydberg molecule in Rb. These states manifest spectroscopical…
High precision spectroscopy of trilobite Rydberg molecules
Markus Exner, Rohan Srikumar, Richard Blättner +3
We perform three-photon photoassociation to obtain high resolution spectra of Rb trilobite dimers for the principal quantum numbers , and . The large bi…
Internal diffraction dynamics of trilobite molecules
Rohan Srikumar, Seth T. Rittenhouse, Peter Schmelcher
Trilobite molecules are ultralong-range Rydberg molecules formed when a high angular momentum Rydberg electron scatters off of a ground-state atom. Their unique electronic structur…
Classical scattering and fragmentation of clusters of ions in helical confinement
Ansgar Siemens, Peter Schmelcher
We explore the scattering dynamics of classical Coulomb-interacting clusters of ions confined to a helical geometry. Ion clusters of equally charged particles constrained to a heli…
