A Hamiltonian for the inclusion of spin effects in long-range Rydberg molecules
Matthew T Eiles, Chris H Greene
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…
Efimov-van-der-Waals universality for ultracold atoms with positive scattering lengths
Paul M. A. Mestrom, Jia Wang, Chris H. Greene +1
We study the universality of the three-body parameters for systems relevant for ultracold quantum gases with positive -wave two-body scattering lengths. Our results account for…
Controlling Rydberg atom excitations in dense background gases
Tara Cubel Liebisch, Michael Schlagmüller, Felix Engel +13
We discuss the density shift and broadening of Rydberg spectra measured in cold, dense atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating back…
Effective Control of Cold Collisions with Radio Frequency Fields
Yijue Ding, Jose P. D'Incao, Chris H. Greene
We study Rb cold collisions in a static magnetic field and a single-color radio frequency (RF) field by employing the multi-channel quantum defect theory in combination with…
Ultracold chemical reactions of a single Rydberg atom in a dense gas
Michael Schlagmüller, Tara Cubel Liebisch, Felix Engel +10
Within a dense environment (atoms/cm) at ultracold temperatures (), a single atom excited to a Rydberg state acts as a reaction center for…
Mapping trilobite state signatures in atomic hydrogen
Jesús Pérez-Ríos, Matthew T Eiles, Chris H Greene
A few-body approach relying on static line broadening theory is developed to treat the spectroscopy of a single Rydberg excitation to a trilobite-like state immersed in a high dens…
Observation of pendular butterfly Rydberg molecules
Thomas Niederprüm, Oliver Thomas, Tanita Eichert +4
Obtaining full control over the internal and external quantum states of molecules is the central goal of ultracold chemistry and allows for the study of coherent molecular dynamics…
Generalized local frame transformation theory for excited species in external fields
P. Giannakeas, Chris H. Greene, F. Robicheaux
A rigorous theoretical framework is developed for a generalized local frame transformation theory (GLFT). The GLFT is applicable to the following systems: to Rydberg atoms or molec…
Ultracold molecular Rydberg physics in a high density environment
Matthew T Eiles, Jesus Perez-Rios, F Robicheaux +1
Sufficiently high densities in Bose-Einstein condensates provide favorable conditions for the production of ultralong-range polyatomic molecules consisting of one Rydberg atom and…
