Long-lived metrological spin squeezing Atomic clocks and sensors are among the most precise measurement instruments in the world, but they can still be improved. Indeed, all of them so far use uncorrelated atoms, creating statistical noise known as quantum projection...
The adjustment of fundamental constants: a tool for new physics searches The values of fundamental constants such as the fine-structure constant, the mass of the electron or proton, the Rydberg constant, are determined by a variety of high-precision experiments:...
