151. Gravitational Wave Detectors Based on Matter Wave Interferometers (MIGO) Are No Better Than Laser Interferometers (LIGO)
Published: Date unknown
Authors: A Roura, Dieter Brill, B- L Hu, Charles Misner, William D Phillips

152. Laboratory Experiments for Fundamental Physics in Space
Published: Date unknown
Author: William D Phillips
Abstract: Laboratory Experiments refers generally to active spaceborne experiments as opposed to the equally important passive observation in space of signals coming from more distant sources. My purpose in this presentation is to highlight a number of oppo ...

153. Laser Cooling and Trapping Group - WWW Home Page
Published: Date unknown
Authors: Paul D Lett, Kristian Helmerson, William D Phillips
Abstract: The laser cooling and trapping group studies the physics of laser cooling, electromagnetic trapping and other radiative manipulation of neutral atoms and dielectric particles. These fundamental studies are used to develop applications to new kinds o ...

154. Observation of Persistent Flow of a Bose-Einstein Condensate in a Toroidal Trap
Published: Date unknown
Authors: Changhyun Ryu, Mikkel Andersen, Pierre Clade, Vasant Natarajan, Kristian Helmerson, William D Phillips
Abstract: We have observed the persistent flow of Bose-condensed atoms in a toroidal trap. The flow persists without decay for up to 10 s, limited only by experimental factors such as drift and trap lifetime. The quantized rotation was initiated by transferr ...

155. Quantized Rotation of Atoms From Photons With Orbital Angular Momentum
Published: Date unknown
Authors: Mikkel Andersen, Changhyun Ryu, Pierre Clade, Vasant Natarajan, A Vaziri, Kristian Helmerson, William D Phillips
Abstract: Light can carry two kinds of angular momentum: Spin angular momentum (SAM) associated with its polarization and orbital angular momentum (OAM) associated with its spatial mode [1, 2]. The coupling of optical SAM to atoms has been known for over a cen ...

156. Study of a 1D Interacting Quantum Bose Gas
Published: Date unknown
Authors: B Laburthe, K M O'Hara, J H Huckans, M Anderlini, James V Porto, S L. Rolston, William D Phillips
Abstract: The loading of a Bose-Einstein condensate into a deep 2D optical lattice provides a unique way to study 1D Bose gases: the strong radial confinement freezes any motion in two dimensions, and for deep enough lattices, the system can be seen as an arra ...

157. Subwavelength Addressibility and Spin-Dependent Transport in a Double-Well Optical Lattice
Published: Date unknown
Authors: Patricia J. Lee, M Anderlini, Ben L. Brown, Jennifer Sebby-Strabley, William D Phillips, James V Porto
Abstract: We report the experimental demonstration of site-selective RF addressing of atoms with sub-wavelength resolution in a spin-dependent optical lattice of double wells. We also show spin-dependent transport: coherent spatial separation of atomic wave pa ...

158. Transport of Atoms in a Quantum Conveyor Belt
Published: Date unknown
Authors: A Browaeys, H H ffnert, C R McKenzie, S L. Rolston, Kristian Helmerson, William D Phillips
Abstract: We have performed experiments using a 3D-Bose-Einstein condensate of sodium atoms in a 1D optical lattice to explore some unusual properties of band-structure. In particular, we investigate the loading of a condensate into a moving lattice and find ...
