Modeling atom interferometry experiments with Bose-Einstein condensates in power-law potentials
S. Thomas, C. Sapp, C. Henry +4
Recent atom interferometry (AI) experiments involving Bose--Einstein condensates (BECs) have been conducted under extreme conditions of volume and interrogation time. Numerical sol…
Producing flow in "racetrack" atom circuits by stirring at zero and non-zero temperature
Benjamin Eller, Olatunde Oladehin, Daniel Fogarty +3
We present a study of how macroscopic flow can be produced in Bose-Einstein condensate confined in a "racetrack" potential by stirring with a wide rectangular barrier. This potenti…
Tools for designing atom interferometers in a microgravity environment
Elizabeth Ashwood, Ed Wesley Wells, Doga Murat Kurkcuoglu +3
We present a variational model suitable for rapid preliminary design of atom interferometers in a microgravity environment. The model approximates the solution of the 3D rotating--…
Induced density correlations in a sonic black hole condensate
Yi-Hsieh Wang, Ted Jacobson, Mark Edwards +1
Analog black/white hole pairs, consisting of a region of supersonic flow, have been achieved in a recent experiment by J. Steinhauer using an elongated Bose-Einstein condensate. A…
Entanglement and spin-squeezing without infinite-range interactions
Michael Foss-Feig, Zhe-Xuan Gong, Alexey V. Gorshkov +1
Infinite-range interactions are known to facilitate the production of highly entangled states with applications in quantum information and metrology. However, many experimental sys…
Superfluid transport dynamics in a capacitive atomtronic circuit
Aijun Li, Stephen Eckel, Benjamin Eller +3
We simulate transport in an atomtronic circuit of a Bose-Einstein condensate that flows from a source region into a drain through a gate channel. The time-dependent Gross-Pitaevski…
