An electron spin resonance spectrometer using an artificial atom (a superconducting flux qubit) is realized, featuring both high sensitivity (400 spins/√Hz) and high spatial resolution (0.05 pL).

Everything you see around you is made up of elementary particles called quarks and leptons, which can combine to form bigger particles such as protons or atoms.
But that doesn’t make them boring – these subatomic particles can also combine in exotic ways we’ve never spotted.
Now CERN’s LHCb collaboration has announced the discovery of a clutch of new particles dubbed “pentaquarks”. The results can help unveil many mysteries of the theory of quarks, a key part of the standard model of particle physics.

If you throw a ball at a wall, it’s going to bounce back at you – that’s classical physics at work. But of course, the world of quantum physics is much spookier, so if you did the same with a particle, there’s a chance that it will suddenly appear on the other side. This is thanks to a phenomenon known as quantum tunneling, and now a team of physicists has measured just how long that process takes.
Time may be a human construct but that hasn’t stopped physicists from perfecting it.
JILA’s 3D Quantum Gas Atomic Clock Offers New Dimensions in Measurement
https://www.nist.gov/news-events/news/2017/10/jilas-3-D-quan…easurement
“JILA physicists have created an entirely new design for an atomic clock, in which strontium atoms are packed into a tiny three-dimensional (3D) cube at 1,000 times the density of previous one-dimensional (1-D) clocks. In doing so, they are the first to harness the ultra-controlled behavior of a so-called “quantum gas” to make a practical measurement device.”

About the Presenter:
After getting his Ph.D. in physics from UC San Diego, Garrett moved to Maui, seeking an optimum balance between surfing and his theoretical research. While pursuing an unanswered question at the heart of Quantum Field Theory, he began to develop what he called “An Exceptionally Simple Theory of Everything,” which proposed a unified field theory combining particle physics and Albert Einstein’s theory of gravitation. His story and work have been featured at TED, in Outside Magazine, The New Yorker, Surfer, and recently in Scientific American.

Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding of the structure of matter in the universe.
Assisted by Liming Zhang, an associate professor at Tsinghua University in Beijing, Skwarnicki has analyzed data from the Large Hadron Collider beauty (LHCb) experiment at CERN’s Large Hadron Collider (LHC) in Switzerland. The experimental physicist has uncovered evidence of three never-before-seen pentaquarks, each divided into two parts.
“Until now, we had thought that a pentaquark was made up of five elementary particles [called quarks], stuck together. Our findings prove otherwise,” says Skwarnicki, a Fellow of the American Physical Society.
