Buckyballs Play by Quantum Rules

Published: February 22, 2019 - 9:30am | Source: The Ye Group

A water molecule has three atoms—two hydrogens and one oxygen. But stack three water molecules side by side and you’ve got the width of a buckyball, a complex molecule of 60 carbon atoms. Medium in size and large in atom count, the buckyball has long challenged the idea that only small molecules can play by quantum rules.

And last month we learned that the buckyball plays by full... read more -->

Same Clock. New Perspective.

Published: March 15, 2018 - 3:15pm | Source: The Ye Group

We all know what a tenth of a second feels like. It’s a jiffy, a snap of the fingers, or a camera shutter click. But what does 14 billion years, which is the age of the universe, feel like?

JILA’s atomic clock has the precision to measure the age of the universe to within a tenth of a second. That sort of precision is difficult to intuit. Yet JILA’s atomic clock, which is the most... read more -->

The Energetic Adolescence of Carbon Dioxide

Published: January 12, 2018 - 4:15pm | Source: The Ye Group

The reaction, at first glance, seems simple. Combustion engines, such as those in your car, form carbon monoxide (CO). Sunlight converts atmospheric water into a highly reactive hydroxyl radical (OH). And when CO and OH meet, one byproduct is carbon dioxide (CO2) ­– a main contributor to air pollution and climate change.

But it’s more complicated than that. Before CO2... read more -->

And, The Answer Is . . . Still Round

Why are we here? This is an age-old philosophical question. However, physicists like Will Cairncross, Dan Gresh and their advisors Eric Cornell and Jun Ye actually want to figure out out why people like us exist at all. If there had been the same amount of matter and antimatter created in the Big Bang, the future of stars, galaxies, our Solar System, and life would have disappeared in a flash... read more -->
