11. Rapid Production of ^87^Rb BECs in a Combined Magnetic and Optical Potential
Published: 8/31/2009
Authors: Yu-Ju Lin, Abigail Reiko Perry, Robert L. Compton, Ian B Spielman, James V Porto
Abstract: We describe an apparatus for quickly and simply producing ^87^Rb Bose-Einstein condensates. It is based on a magnetic quadrupole trap and a red detuned optical dipole trap. We collect atoms in a magneto-optical trap (MOT) and then capture the atom ...

12. Optical Lattice-Based Addressing and Control of Long-Lived Neutral-Atom Qubits
Published: 7/6/2009
Authors: Nathan Lundblad, J Obrecht, Ian B Spielman, James V Porto
Abstract: The establishment of a scalable, addressable, and long-lived scheme for quantum computing would be a scientific watershed, harnessing the laws of quantum physics to solve classically intractable problems. Many proposed computational platforms are dri ...

13. A Bose-Einstein Condensate in a Uniform Light-Induced Vector Potential
Published: 3/30/2009
Authors: Yu-Ju Lin, Robert L. Compton, Abigail Reiko Perry, William D Phillips, James V Porto, Ian B Spielman
Abstract: 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 states in this Raman field are spin and momentum superpositions, and we adiabatically load ...

14. Improving Correlations with Inelastic Loss
Published: 6/6/2008
Author: James V Porto
Abstract: Correlations are one of the central features of modern condensed matter physics. They arise in systems where the behavior of any given particle in a system depends strongly on all the other particles. Such correlations are what help distinguish the r ...

15. Controlled Exchange Interaction Between Pairs of Neutral Atoms in an Optical Lattice
Published: 7/26/2007
Authors: M Anderlini, Patricia J. Lee, Ben L. Brown, Jennifer Sebby-Strabley, William D Phillips, James V Porto
Abstract: Ultra-cold atoms trapped by light, with their inherent quantum coherence and controllability, provide an attractive system for quantum information and for the simulation of complex problems in condensed matter physics. Quantum information processing ...

16. Preparing and Probing Atomic Number States With an Atom Interferometer
Published: 5/17/2007
Authors: Jennifer Sebby-Strabley, Ben L. Brown, M Anderlini, Patricia J. Lee, William D Phillips, James V Porto, Philip R Johnson
Abstract: We describe the controlled loading and measurement of number-squeezed states and Poisson states in individual sites of a double well optical lattice. These states are input to an atom interferometer that is realized by symmetrically splitting individ ...

17. The Mott Insulator Transition in a Two Dimensional Atomic Bose Gas
Published: 2/22/2007
Authors: Ian B Spielman, William D Phillips, James V Porto
Abstract: Cold atoms confined in periodic potentials are remarkably versatile quantum systems for implementing simple models prevalent in condensed matter theory. Here we realize the 2D Bose-Hubbard model by loading a Bose-Einstein condensate into an optical l ...
