Prethermal ripplons in quenched binary Bose-Einstein condensates
Yanda Geng, Stephen Eckel, Gretchen K. Campbell +1
Prethermal states--long-lived quasi-equilibrium configurations--occur in a wide range of physical systems that exhibit fast dephasing or reconfiguration followed by slow relaxation…
Sawtooth wave adiabatic passage in a grating magneto-optical trap
Peter K. Elgee, Ananya Sitaram, Sara Ahanchi +4
We demonstrate sawtooth wave adiabatic passage (SWAP) in a grating magneto-optical trap (MOT) operating on the S P transition of neutral Sr. Fr…
Efficient production of sodium Bose-Einstein condensates in a hybrid trap
Yanda Geng, Shouvik Mukherjee, Swarnav Banik +6
We describe an apparatus that efficiently produces Na Bose-Einstein condensates (BECs) in a hybrid trap that combines a quadrupole magnetic field with a far-detuned optical…
The Rayleigh-Taylor instability in a binary quantum fluid
Yanda Geng, Junheng Tao, Mingshu Zhao +4
Instabilities, where small fluctuations seed the formation of large-scale structures, govern dynamics in a variety of fluid systems. The Rayleigh-Taylor instability (RTI), present…
Grating magneto-optical traps with complicated level structures
D. S. Barker, P. K. Elgee, A. Sitaram +4
We study the forces and optical pumping within grating magneto-optical traps (MOTs) operating on transitions with non-trivial level structure. In contrast to the standard six-beam…
Accurate Determination of Hubble Attenuation and Amplification in Expanding and Contracting Cold-Atom Universes
S. Banik, M. Gutierrez Galan, H. Sosa-Martinez +4
In the expanding universe, relativistic scalar fields are thought to be attenuated by "Hubble friction", which results from the dilation of the underlying spacetime metric. By cont…
Confinement of an alkaline-earth element in a grating magneto-optical trap
A. Sitaram, P. K. Elgee, G. K. Campbell +3
We demonstrate a compact magneto-optical trap (MOT) of alkaline-earth atoms using a nanofabricated diffraction grating chip. A single input laser beam, resonant with the broad …
A flexible, open-source radio-frequency driver for acousto-optic and electro-optic devices
D. S. Barker, N. C. Pisenti, A. Restelli +4
We present a design for a radio-frequency driver that leverages telecom amplifiers to achieve high power output and wide bandwidth. The design consists of two compact printed circu…
Resonant wavepackets and shock waves in an atomtronic SQUID
Yi-Hsieh Wang, A. Kumar, F. Jendrzejewski +5
The fundamental dynamics of ultracold atomtronic devices are reflected in their phonon modes of excitation. We probe such a spectrum by applying a harmonically driven potential bar…
Enhanced Magnetic Trap Loading for Atomic Strontium
D. S. Barker, B. J. Reschovsky, N. C. Pisenti +1
We report on a technique to improve the continuous loading of atomic strontium into a magnetic trap from a Magneto-Optical Trap (MOT). This is achieved by adding a depumping laser…
Resistive flow in a weakly interacting Bose-Einstein condensate
F. Jendrzejewski, S. Eckel, N. Murray +4
We report the direct observation of resistive flow through a weak link in a weakly interacting atomic Bose-Einstein condensate. Two weak links separate our ring-shaped superfluid a…
Probing the circulation of ring-shaped Bose-Einstein condensates
Noel Murray, Michael Krygier, Mark Edwards +3
This paper reports the results of a theoretical and experimental study of how the initial circulation of ring-shaped Bose-Einstein condensates (BECs) can be probed by time-of-fligh…
Rabi Spectroscopy and Excitation Inhomogeneity in a 1D Optical Lattice Clock
S. Blatt, J. W. Thomsen, G. K. Campbell +5
We investigate the influence of atomic motion on precision Rabi spectroscopy of ultracold fermionic atoms confined in a deep, one dimensional (1D) optical lattice. We analyze the s…
