Reducing Rydberg state dc polarizability by microwave dressing
J. C. Bohorquez, R. Chinnarasu, J. Isaacs +4
We demonstrate reduction of the dc polarizability of Cesium atom Rydberg states in a 77 K environment utilizing microwave field dressing. In particular we reduce the polarizability…
Tracking evaporative cooling of a mesoscopic atomic quantum gas in real time
Johannes Zeiher, Julian Wolf, Joshua A. Isaacs +2
The fluctuations in thermodynamic and transport properties in many-body systems gain importance as the number of constituent particles is reduced. Ultracold atomic gases provide a…
Collisional spin transfer in an atomic heteronuclear spinor Bose gas
Fang Fang, Joshua A. Isaacs, Aaron Smull +5
We observe spin transfer within a non-degenerate heteronuclear spinor atomic gas comprised of a small Li population admixed with a Rb bath, with both elements in their $…
Cross-dimensional relaxation of Li-Rb atomic gas mixtures in a spherical-quadrupole magnetic trap
Fang Fang, Shun Wu, Aaron Smull +4
We measure the interspecies interaction strength between Li and Rb atoms through cross-dimensional relaxation of two-element gas mixtures trapped in a spherical quadrupo…
Reducing the sensitivity of Rydberg atoms to dc electric fields using two-frequency ac field dressing
Donald W. Booth, Joshua Isaacs, M. Saffman
We propose a method for reducing the sensitivity of atomic ground to Rydberg transitions to stray dc electric fields, using microwave-induced dressing of Rydberg states. Calculatio…
Long working distance objective lenses for single atom trapping and imaging
J. D. Pritchard, J. A. Isaacs, M. Saffman
We present a pair of optimized objective lenses with long working distances of 117~mm and 65~mm respectively that offer diffraction limited performance for both Cs and Rb wavelengt…
Impact of post-Born lensing on the CMB
Geraint Pratten, Antony Lewis
Lensing of the CMB is affected by post-Born lensing, producing corrections to the convergence power spectrum and introducing field rotation. We show numerically that the lensing co…
Hybrid Atom--Photon Quantum Gate in a Superconducting Microwave Resonator
J. D. Pritchard, J. A. Isaacs, M. A. Beck +2
We propose a novel hybrid quantum gate between an atom and a microwave photon in a superconducting coplanar waveguide cavity by exploiting the strong resonant microwave coupling be…
Atom trapping in a bottle beam created by a diffractive optical element
V. V. Ivanov, J. A. Isaacs, M. Saffman +6
A diffractive optical element (DOE) has been fabricated for creating blue detuned atomic bottle beam traps. The DOE integrates several diffractive lenses for trap creation and imag…
