A three-cornered hat analysis has been performed on three independent time transfer systems between the United States Naval Observatory (USNO) and the National Institute of Standards and Technology (NIST). These include (1) a direct Two-Way Satellite

One of the central paradigms for classical and quantum chaos in conservative systems is the two-dimensional billiard in which particles are confined to a closed region in the plane, undergoing elastic collisions with the walls and free motion in betw

We report the direct observation of sub-Poissonian number fluctuation for a degenerate Bose gas confined in an optical trap. Reduction of number fluctuations below the Poissonian limit is observed for average numbers that range from 300 to 60 atoms.<

We present an experimental method to create a single high frequency optical trap for atoms based on an elongated Hermite-Gaussian TEM01 mode beam. This trap results in confinement strength similar to that which may be obtained in an optical lattice.

One-dimensional Bose-Einstein condensates have been produced in an optical box trap. Integrated with single atom detection capability, the box trap paves the way for studies of quantum atom statistics.

Bose-Einstein condensates have been produced in an optical box trap. This novel optical trap type has strong confinement in two directions comparable to that which is possible in an optical lattice, yet produces individual condensates rather than the

We demonstrate real-time feedback control of atomic center of mass motion in a cloud of laser cooled cesium atoms. Using the velocity measurement technique of recoil-induced resonances, the average velocity of the atomic cloud is obtained. This infor

The distal part of a percutaneous translumenal coronary angioplasty (PTCA) guidewire should not only be flexible, nonkinking, radiopaque and lubricious, but also nonthrombogenic. Possible formation of thrombotic emboli at a guidewire's surface enhanc
