New Experimental Limits on Macroscopic Forces Below 100 Microns
Joshua C. Long, Hilton W. Chan, Allison B. Churnside +3
Results of an experimental search for new macroscopic forces with Yukawa range between 5 and 500 microns are presented. The experiment uses 1 kHz mechanical oscillators as test mas…
Observation of Collective-Emission-Induced Cooling inside an Optical Cavity
Hilton W. Chan, Adam T. Black, Vladan Vuletic
We report the observation of collective-emission-induced, velocity-dependent light forces. One third of a falling sample containing 3 x 10^6 cesium atoms illuminated by a horizonta…
Taber Vibration Isolator for Vacuum and Cryogenic Applications
Hilton W. Chan, Joshua C. Long, John C. Price
We present a procedure for the design and construction of a passive, multipole, mechanical high-stop vibration isolator. The isolator, consisting of a stack of metal disks connecte…
Experimental Status of Gravitational-Strength Forces in the Sub-Centimeter Regime
Joshua C. Long, Hilton W. Chan, John C. Price
We review the experimental constraints on additional macroscopic Yukawa forces for interaction ranges below 1 cm., and summarize several theoretical predictions of new forces in th…
