We have produced and characterized an intense, slow, and highly collimated atomic beam extracted from a standard vapor cell magneto-optical trap (MOT).The technique used is dramatically simpler than… Expand

Interference of atomic de Broglie waves tunneling from a vertical array of macroscopically populated traps has been observed, closely related to the ac Josephson effect observed in superconducting electronic systems.Expand

The ratio h/m' of Planck's constant to the observable Cooper-pair mass (approx.2m/sub e/) is determined directly using a rotating superconducting ring by measuring the London moment flux (2m'c/e/sup… Expand

We consider a class of singlet resonating-valence-bond wave functions on a square lattice, with the bond-length distribution as a variational parameter. This class contains the two limiting cases of… Expand

The resulting general expressions of the conservation laws enjoy important invariance properties and synthesize all known asymptotic conservation laws, such as the Arnowitt-Deser-Misner energy in general relativity.Expand

In this paper we show that the development of resonating valence bond correlations and the subsequent superconducting order in the high-T/sub c/ oxide superconductors are described by an U(1) lattice… Expand

Baryogenesis at the electroweak phase transition is tenable in minimal extensions of the standard model with one Higgs doublet because the rate of anomalous baryon-number violation is an exponentially sensitive function of 〈\ensuremath{\varphi}${〉}}_{\mathit{T}}$.Expand

This is the first test of the solar redshift with an interplanetary spacecraft and it is verified the total frequency shift predicted by general relativity to 0.5% accuracy, and the solar gravitational redshift to 1% accuracy.Expand
