Atomic Clock Comparison Confirms Key assumptions of ‘Einstein’s Elevator’

This image, taken with the Wide Field Camera 3 (WFC3) and the Advanced Camera for Surveys (ACS), both installed on the NASA/ESA Hubble Space Telescope, shows the peculiar galaxy NGC 3256. The galaxy is about 100 million light-years from Earth and is the result of a past galactic merger, which created its distorted appearance. As such, NGC 3256 provides an ideal target to investigate starbursts that have been triggered by galaxy mergers. Credit: ESA/Hubble, NASA

By comparing different types of remote atomic clocks, physicists at the National Institute of Standards and Technology (NIST) have performed the most accurate test ever of a key principle underlying Albert Einstein’s famous theory of general relativity, which describes how gravity relates to space and time...

Atomic Clock mimics long-sought synthetic Magnetic State

JILA physicists used a strontium lattice atomic clock to simulate magnetic properties long sought in solid materials. The atoms are confined in an optical lattice, shown as an array of disk-shaped traps set at shallow depths. A laser (yellow wave) probes the atoms to couple the atoms' spins and motions. The two atomic spin states are illustrated in red and blue. Credit: Steven Burrows and Ye Group/JILA

JILA physicists have caused atoms in a gas to behave as if they possess unusual magnetic properties long sought in harder-to-study solid materials. Representing a novel “off-label” use for atomic clocks, the research could lead to the creation of new materials for applications such as “spintronic” devices and quantum computers...
