High densities of cold atoms in a dark spontaneous-force optical trap.
A new magneto-optical trap is demonstrated which confines atoms predominantly in a «dark» hyperfine level, that does not interact with the trapping light. This leads to much higher atomic densitiesExpand

  • 23 November 1993
We compute the two-loop renormalization group equations for all soft supersymmetry-breaking couplings in a general softly broken N = 1 supersymmetric model. We also specialize these results to theExpand

Noise in conductors transmitting electrons coherently between attached reservoirs is calculated by following wave packets incident on the sample. The Pauli principle restricts the occupation of waveExpand
Theoretical calculations of heterojunction discontinuities in the Si/Ge system.
We present a theoretical study of the structural and electronic properties of pseudomorphic Si/Ge interfaces, in which the layers are strained such that the lattice spacing parallel to the interfaceExpand

Parton distributions for the pion extracted from Drell-Yan and prompt photon experiments.
We determine the parton distributions of the pion from a consistent next-to-leading-order analysis of several high-statistics π ± N experiments including both Drell-Yan and prompt photon production
Viscous bursting of suspended films.
Soap films break up by an inertial process. We present here the first observations on freely suspended films of long-chain polymers, where viscous effects are dominant and no surfactant is present. AExpand
Search for supersymmetry with a light gravitino at the Fermilab Tevatron and CERN LEP colliders.
We analyze the prospects for discovering supersymmetry at the Fermilab Tevatron and CERN LEP colliders in the scenario that the lightest supersymmetric particle is a gravitino of mass {approx_lt}1Expand
Generalized Field Propagator for Electromagnetic Scattering and Light Confinement.
We present a new theoretical and numerical framework for the study of the optical properties of micrometric and nanometric three-dimensional structures of arbitrary shape. We show that the fieldExpand
First-principles study of the atomic reconstructions and energies of Ga- and As-stabilized GaAs(100) surfaces.

  • 15 October 1988
We have carried out ab initio total-energy density-functional calculations to study the reconstructions of GaAs(100) surfaces as a function of Ga and As surface coverage. Equilibrium atomicExpand
