Time dependence of few-body Förster interactions among ultracold Rydberg atoms
Zhimin Cheryl Liu, Nina P. Inman, Thomas J. Carroll +1
Rubidium Rydberg atoms in either -sublevel of the state can exchange energy via Stark-tuned Förster resonances, including two-, three-, and four-body dipole-dipo…
Perturbed Field Ionization for Improved State Selectivity
Vincent C. Gregoric, Jason J. Bennett, Bianca R. Gualtieri +9
Selective field ionization is used to determine the state or distribution of states to which a Rydberg atom is excited. By evolving a small perturbation to the ramped electric fiel…
Improving the state selectivity of field ionization with quantum control
Vincent C. Gregoric, Jason J. Bennett, Bianca R. Gualtieri +5
The electron signals from the field ionization of two closely-spaced Rydberg states of \mbox{rubidium-85} are separated using quantum control. In selective field ionization, the st…
Quantum control via a genetic algorithm of the field ionization pathway of a Rydberg electron
Vincent C. Gregoric, Xinyue Kang, Zhimin Cheryl Liu +3
Quantum control of the pathway along which a Rydberg electron field ionizes is experimentally and computationally demonstrated. Selective field ionization is typically done with a…
Simulations of the angular dependence of the dipole-dipole interaction among Rydberg atoms
Jacob L. Bigelow, Jacob T. Paul, Matan Peleg +3
The dipole-dipole interaction between two Rydberg atoms depends on the relative orientation of the atoms and on the change in the magnetic quantum number. We simulate the effect of…
Simulations of the Dipole-Dipole Interaction between Two Spatially Separated Groups of Rydberg Atoms
T. J. Carroll, C. Daniel, L. Hoover +2
The dipole-dipole interaction among ultra-cold Rydberg atoms is simulated. We examine a general interaction scheme in which two atoms excited to the x and x' states are converted t…
