A particularly well-ordered kind of laser light can be created by turbulence, which is usually responsible for very disordered phenomena.

New quasi-particle discovered: the Pi-ton

The team

Actually they had been looking for something completely different, but they found a previously unknown quasi-particle: A bound state of two electrons,…

How Nature Tells us its Formulas

A multi-particle system

Developing a quantum description for a many-body system is extremely hard. TU Wien (Vienna) and Heidelberg University found a way to obtain quantum…

How to Take a Picture of a Light Pulse

Two laser pulses hit silicon dioxide

Until now, complex experimental equipment was required to measure the shape of a light pulse. A team from TU Wien (Vienna), MPI Garching and LMU…

A metronome for quantum particles

A new measurement protocol, developed at TU Wien (Vienna), makes it possible to measure the quantum phase of electrons - an important step for…

Measuring the Laws of Nature

Experimental equipment at ILL Grenoble

A physical constant, which is of great importance for basic research, has now be re-measured, with much higher precision than ever before.
