Studying the quantum vacuum: Traffic jam in empty space

An important step towards a completely new experimental access to quantum physics has been made at University of Konstanz. The team of scientists headed by Professor Alfred Leitenstorfer has now shown how to manipulate the ...

Quantum membranes for ultraprecise mechanical measurements

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how quantum fluctuations set a sensor ...

Quantum particles form droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: the atoms form a new type of quantum liquid or quantum droplet state. These so called quantum ...

Finding patterns in 'electron puddles'

Yale physicist Leonid Glazman has developed a quantitative theory to explain the effect of quantum and thermal fluctuations of charge in tiny "electron puddles" for a study reported in the journal Nature.

Bringing the chaos in light sources under control

Noise is an issue in optical telecommunications. And findings means of controlling noise is key to physicists investigating light-emitting diodes or lasers. Now, an Italo-Iraqi team has worked on a particular type of light ...

Scientists 'squeeze' light one particle at a time

A team of scientists has successfully measured particles of light being "squeezed", in an experiment that had been written off in physics textbooks as impossible to observe.

Detector at the South Pole explores the mysterious neutrinos

Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The Earth is constantly bombarded by billions of neutrinos, which zip right through ...
