Verkehr und Geräuschentwicklung gehören zumindest bisher untrennbar zusammen. Insofern ist es vielleicht kein Zufall, dass gerade in der Region Südostniedersachsen, wo sich in Wirtschaft und Forschung vieles um Autos, Flugzeuge und Verkehr dreht, auch besonders viel akustische Kompetenz zu finden ist. Nur waren die akustische Forschung und Lehre bisher auf viele einzelne renommierte...

While scientists often explore the very smallest of dimensions, colossal objects weighing several tons are soon to play an important role as well: the Physikalisch-Technische Bundesanstalt (PTB) plans to measure large gears of up to four meters in diameter in its future excellence center for wind energy. Its goal in doing so is to develop and make available a form of measurement technology which...

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. As early as 1981, Hans Dehmelt, who was to be awarded a Nobel prize later, had already developed the basic notions of how to use an ion kept in a high-frequency...

Researchers from the Physikalisch-Technische Bundesanstalt (PTB) have thoroughly analyzed the noise processes in their optical lattice clock with neutral strontium atoms. This analysis proves that their optical atomic clock has reached the best stability worldwide thanks to a newly developed laser system whose frequency is extremely stable. This allows high-precision measurements in a short time...

The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees of freedom – in particular the rotational quantum state – are also influenced by the thermal radiation. So far, the detection of the rotational state was only possible by...

Vom 1. August bis zum 30. September 2016 können Studierende in aktuellen Forschungsprojekten der Physikalisch-Technischen Bundesanstalt (PTB) mitarbeiten. Das Motto lautet: „Dein genauester Sommer!“ Von der Grundlagenforschung bis zur technischen Zusammenarbeit – wer sich dafür begeistern kann, zwei Monate lang intensiv und gemeinsam mit hochqualifizierten Kolleginnen und Kollegen an interessanten...
