JILA’s Superradiant Laser May One Day Boost Atomic Clocks and ‘Rulers’ for Space
JILA Superradiant Laser Atomic Clocks Rulers Space
2016/11/4
JILA physicists have demonstrated a novel laser design based on synchronized emissions of light from the same type of atoms used in advanced atomic clocks. The laser could be stable enough to improve ...
Working with a team of scientists from the Technical University of Munich (TU Munich), Brandeis University, and Leiden University in the Netherlands, M. Cristina Marchetti and Mark Bowick, professors ...
HOUSTON – (Jan. 30, 2014) – Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly...
Rydberg Spectroscopy in an Optical Lattice: Blackbody Thermometry for Atomic Clocks
Rydberg Spectroscopy Optical Lattice Blackbody Thermometry Atomic Clocks

Abstract: We show that optical spectroscopy of Rydberg states can provide accurate {\em in situ} thermometry at room-temperature. Transitions from a metastable state to Rydberg states with principal q...
A New Rb Lamp Exciter Circuit for Rb atomic clocks and Studies on Transition from Ring to Red mode
Rb Lamp Exciter Circuit Rb atomic clocks

We report on frequency comparison of two optical lattice clocks based on fermionic 87Sr trapped in 1D optical lattice and bosonic 88Sr in 3D one. We discuss that these two lattice clock configurations...
Galileo noted in the 16th century that the period of oscillation of a pendulum is almost independent of the amplitude. However, such a pendulum is damped by air friction. The latter may be viewed as r...
6 December 2006，Physicists in the US have created a highly-stable optical clock that could push the precision of these new timekeepers beyond that of conventional atomic clocks. Optical clocks keep ti...
