Photon thermalization via laser cooling of atoms

Author(s)
Chiao-Hsuan Wang, Michael Gullans, James V. Porto, William D. Phillips, Jacob M. Taylor
The cooling of atomic motion by scattered light enables a wide variety of technological and scientific explorations. Here we focus on laser cooling from the

An introduction to the new SI

Author(s)
Peter J. Mohr, Sandra Knotts, William D. Phillips
Plans are underway to redefine the International System of Units (SI) around 2018. The new SI specifies the values of certain physical constants to define units

Dimensionless units in the SI

Author(s)
Peter J. Mohr, William D. Phillips
The International System of Units (SI) is supposed to be coherent. That is, when a combination of units is replaced by an equivalent unit, there is no

Hysteresis in Quantized Superfluid Atomtronic Circuit

Author(s)
Stephen P. Eckel, Jeffrey Lee, Fred Jendrzejewski, Noel Murray, Charles W. Clark, Christopher J. Lobb, William D. Phillips, Edwards Mark, Gretchen K. Campbell
Atomtronics is an emerging interdisciplinary field that seeks new functionality by creating devices and circuits where ultra-cold atoms play a role analogous to

Controlling Atomic Interactions with Light

Author(s)
Ross A. Williams, Lindsay J. LeBlanc, Karina K. Jimenez Garcia, Matthew C. Beeler, Abigail R. Perry, William D. Phillips, Ian B. Spielman
For the majority of the 20th century atomic physicists used light to probe and understand atoms. Today, scientists use light to manipulate particles with

Observation of a superfluid Hall effect

Author(s)
Lindsay J. LeBlanc, Karina K. Jimenez Garcia, Ross A. Williams, Matthew C. Beeler, Abigail R. Perry, William D. Phillips, Ian B. Spielman
Measurement techniques based upon the Hall effect are essential tools in condensed matter physics. Here, we report the first observation of a Hall effect in an

Beyond s-wave scattering for ultracold atoms

Author(s)
Ross A. Williams, Lindsay J. LeBlanc, Karina K. Jimenez Garcia, Matthew C. Beeler, Abigail R. Perry, William D. Phillips, Ian B. Spielman
Interactions between particles can be strongly altered by their environment. Here we demonstrate a technique for modifying interactions between ultracold atoms

Ultracold Atoms and Precise Time Standards

Author(s)
Gretchen K. Campbell, William D. Phillips
Experimental techniques of laser cooling and trapping, along with other cooling techniques have produced gaseous samples of atoms so cold that they are, for

Synthetic Electric and Magnetic Fields for Ultracold Neutral Atoms

Author(s)
William D. Phillips, Yu-Ju Lin, Robert L. Compton, Karina K. Jimenez Garcia, Abigail R. Perry, James V. Porto, Ian B. Spielman
We use Raman coupling between magnetic sublevels of a 87Rb Bose-Einstein condensate (BEC) to create an effective vector gauge field for the neutral atoms. They

A Bose-Einstein Condensate in a Uniform Light-Induced Vector Potential

Author(s)
Yu-Ju Lin, Robert L. Compton, Abigail R. Perry, William D. Phillips, James V. Porto, Ian B. Spielman
We use a two-photon dressing field to create an effective vector gauge potential for Bose-condensed ^87Rb atoms in the F=1 hyperfine ground state. The dressed

Atoms in a Radio-Frequency-Dressed Optical Lattice

Author(s)
Ian B. Spielman, James V. Porto, William D. Phillips, Ben Brown, Patricia Lee, Nathan Lundblad
We load cold atoms into an optical lattice dramatically reshaped by radio-frequency coupling of statedependent lattice potentials. This radio-frequency dressing

Preparing and Probing Atomic Number States With an Atom Interferometer

Author(s)
Jennifer Sebby-Strabley, Ben L. Brown, M Anderlini, Patricia J. Lee, William D. Phillips, James V. Porto, Philip R. Johnson
We describe the controlled loading and measurement of number-squeezed states and Poisson states in individual sites of a double well optical lattice. These
