Squeezing Towards the Heisenberg Limit with Locally Interacting Spins
Nazli Ugur Koyluoglu, Shankari V. Rajagopal, Gabriel L. Moreau +3
We propose a robust approach to spin squeezing with local interactions that approaches the Heisenberg limit of phase sensitivity. To generate the requisite entanglement, we general…
Spin Squeezing by Rydberg Dressing in an Array of Atomic Ensembles
Jacob A. Hines, Shankari V. Rajagopal, Gabriel L. Moreau +4
We report on the creation of an array of spin-squeezed ensembles of cesium atoms via Rydberg dressing, a technique that offers optical control over local interactions between neutr…
Number Partitioning with Grover's Algorithm in Central Spin Systems
Galit Anikeeva, Ognjen Marković, Victoria Borish +7
Numerous conceptually important quantum algorithms rely on a black-box device known as an oracle, which is typically difficult to construct without knowing the answer to the proble…
Phasonic Spectroscopy of a Quantum Gas in a Quasicrystalline Lattice
Shankari V. Rajagopal, Toshihiko Shimasaki, Peter Dotti +5
Phasonic degrees of freedom are unique to quasiperiodic structures, and play a central role in poorly-understood properties of quasicrystals from excitation spectra to wavefunction…
Transverse-Field Ising Dynamics in a Rydberg-Dressed Atomic Gas
Victoria Borish, Ognjen Marković, Jacob A. Hines +2
We report on the realization of long-range Ising interactions in a cold gas of cesium atoms by Rydberg dressing. The interactions are enhanced by coupling to Rydberg states in the…
Quantifying and controlling prethermal nonergodicity in interacting Floquet matter
Kevin Singh, Cora J. Fujiwara, Zachary A. Geiger +10
The use of periodic driving for synthesizing many-body quantum states depends crucially on the existence of a prethermal regime, which exhibits drive-tunable properties while fores…
Transport in Floquet-Bloch bands
C. J. Fujiwara, Kevin Singh, Zachary A. Geiger +4
We report Floquet band engineering of long-range transport and direct imaging of Floquet-Bloch bands in an amplitude-modulated optical lattice. In one variety of Floquet-Bloch band…
Observation and uses of position-space Bloch oscillations in an ultracold gas
Zachary A. Geiger, Kurt M. Fujiwara, Kevin Singh +8
We report the direct observation and characterization of position-space Bloch oscillations using an ultracold gas in a tilted optical lattice. While Bloch oscillations in momentum…
Experimental Realization of a Relativistic Harmonic Oscillator
Kurt M. Fujiwara, Zachary A. Geiger, Kevin Singh +5
We report the experimental study of a harmonic oscillator in the relativistic regime. The oscillator is composed of Bose-condensed lithium atoms in the third band of an optical lat…
Quantum Simulation of Ultrafast Dynamics Using Trapped Ultracold Atoms
Ruwan Senaratne, Shankari V. Rajagopal, Toshihiko Shimasaki +5
Ultrafast electronic dynamics are typically studied using pulsed lasers. We demonstrate a complementary experimental approach: quantum simulation of ultrafast dynamics using trappe…
Quantum Emulation of Extreme Non-equilibrium Phenomena with Trapped Atoms
Shankari V. Rajagopal, Kurt M. Fujiwara, Ruwan Senaratne +3
Ultracold atomic physics experiments offer a nearly ideal context for the investigation of quantum systems far from equilibrium. We describe three related emerging directions of re…
Effusive Atomic Oven Nozzle Design Using an Aligned Microcapillary Array
Ruwan Senaratne, Shankari V. Rajagopal, Zachary A. Geiger +3
We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this desi…
