Researchers demonstrate direct comparison of spin-squeezed optical lattice clocks at record precision level
Optical Lattice Clock at JILA, Boulder. Credit: JILA Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from…
STAR Physicists Track Sequential ‘Melting’ of Upsilons
The Science Scientists use the Relativistic Heavy Ion Collider (RHIC), a Department of Energy user facility, to recreate and study the hot particle soup that existed in the very early universe. Recent…
Getting to the Bottom of When the Smallest Meson Melts
The Science Theorists have performed calculations to predict the temperature at which bottomonium mesons will melt. Bottomonium mesons are particles made of one of the six types of quark: a…
