Coauthored the gallium arsenide junction laser study, identifying interference fringes above threshold as evidence of a definite optical phase relation. [ref]
Coherent Light Emission From GaAs Junctions by R. N. Hall and others. Page 366: authors and Fig. 1 discussion.
Coauthored the gallium arsenide junction laser experiment, where emission narrowed sharply above the electrical threshold, supporting the onset of stimulated emission. [ref]
Coherent Light Emission From GaAs Junctions by R. N. Hall and others. Pages 366–367: authors, threshold and Fig. 2.
Coauthored the gallium arsenide junction laser study, using parallel polished crystal faces to provide feedback for the emitting junction. [ref]
Coherent Light Emission From GaAs Junctions by R. N. Hall and others. Page 366: authors and resonant-cavity construction.
Coauthored the gallium arsenide junction laser experiment, using pulsed electrical injection and liquid-nitrogen cooling to produce coherent infrared emission. [ref]

Coauthored the fractional-charge experiment in which the crossover between shot noise and Johnson-Nyquist noise independently supported an effective carrier charge of . [ref]
Coauthored the fractional quantum Hall effect experiment in a gallium arsenide electron system, using a quantum point contact to control the backscattered current and its shot noise. [ref]

Coauthored a fractional quantum Hall effect experiment using shot noise to measure tunnelling carriers with electric charge at filling factor . [ref]
A physicist associated with research on laser cooling. His NIST account explains how measured atomic temperatures fell below the limit predicted by a simple Doppler cooling model. The discrepancy led to a more detailed explanation involving atomic internal states and spatially varying light polarization, including Sisyphus cooling. The episode shows why measuring the velocity distribution was essential: a model adequate for slowing an atomic beam did not capture all the processes operating in an optical cooling experiment.[ref]
Observation of Atoms Laser-Cooled Below the Doppler Limit by Steven Rolston. Historical account: time-of-flight temperature measurements, failure of the simple Doppler limit and polarization-gradient explanation

Coauthored the reactor electron antineutrino confirmation. Halving the target proton density halved the signal, supporting its interpretation as inverse beta decay.[ref]

Coauthored the electron antineutrino experiment using coincidence counting in layered scintillators, with prompt positron annihilation followed by delayed neutron capture in cadmium.[ref]
Detection of the Free Neutrino: a Confirmation by Clyde Cowan and others. Pages 103–104: authors and apparatus
Coauthored the reactor electron antineutrino confirmation using inverse beta decay. Prompt positron annihilation and delayed neutron capture supplied a distinctive paired signal.[ref]

Coauthored nuclear magnetic resonance measurements of liquid helium-3 in which a shifted resonance appeared below about mK; near mK it disappeared and the liquid absorption dropped to roughly half. [ref]
New Magnetic Phenomena in Liquid He3 below 3 mK by Douglas Dean Osheroff and others. Pages 920–922: authors, abstract and Figs. 1–2.
Institutional source issuer.
Coauthored observations of electron-muon pairs with missing energy in electron-positron annihilation. Their analysis required at least two unobserved particles in each event.[ref]
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
