New Atomic Clock Redefines Time

We all know atomic clocks keep the most accurate time of any clock out there– but our idea of time is about to get a whole lot more precise. It’s called an optical lattice clock, and trust us, it’s gonna rock your world!

Precise atomic clock may redefine time

“The international definition of a second of time could be heading for a change, thanks to researchers who have demonstrated that an advanced type of ‘atomic clock’ has the degree of precision and stability needed to provide a new standard.”

Experimental realization of an optical second with strontium lattice clocks

“Progress in realizing the SI second had multiple technological impacts and enabled further constraint of theoretical models in fundamental physics.”

Strontium optical clock

“Atomic fountains using cold cesium atoms, currently defining the second from a microwave atomic transition, will soon reach their ultimate accuracy.”

The Importance of the Atomic Clock

“Most people have vaguely heard of the atomic clock and presume they know what one is but very few people know just how important atomic clocks are for the running of our day to day lives in the twenty first century.”

Atomic Clock Applications – Dr. David Wineland

Atomic Clocks and the 2012 Physics Nobel Prize

“The Nobel Prize in Physics this year was awarded to Serge Haroche and David Wineland for their ground breaking work on the manipulation and measurement of single quantum particles. Wineland’s major contribution has been the development of atomic clocks using a single trapped and laser cooled ion.”

Space Segment

“The GPS space segment consists of a constellation of satellites transmitting radio signals to users. The Air Force manages the constellation to ensure the availability of at least 24 GPS satellites, 95% of the time.”

Holding antimatter is exciting step for physics

“On June 7, the Daily Cal reported on the demonstrated trapping of long-lived antihydrogen atoms by the Antihydrogen Laser Physics Apparatus collaboration, which includes members of the Fajans and Wurtele research groups in the UC Physics department.”



The Search for Antimatter

“The big bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?”

Matter vs. antimatter: particle accelerator experiment says matter wins

“The seemingly inescapable fact that matter and antimatter particles destroy each other on contact has long puzzled physicists wondering how life, the universe or anything else can exist at all. But new results from a particle accelerator experiment suggest that matter does seem to win in the end.”

What is an atomic clock and how does it work?

“If you have read How GPS Receivers Work, you know that atomic clocks are extremely important to the system.”
