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…
