Gateway for scientists


Here you will find current news from PTB's diverse research activities as well as a short guide to PTB.


Scientists at the QUEST Institute at Leibniz University, Hannover, and the PTB, have, together with colleagues at the institute of Theoretical Physics at the Leibniz University, Hannover, and with colleagues of the National Institute of Optics in Florence, Italy, introduced a method based on a non-classical state adapted to two measurement parameters at once. This will enable precision measurements of molecules which could reveal interactions between conventional and dark matter. They report on their results in the current issue of Nature Communications.

Walther Meißner, der Pionier der Tieftemperaturforschung, ist der Namenspatron des neuen Gebäudes, das die Physikalisch-Technische Bundesanstalt (PTB) auf ihrem historischen Gelände in Berlin-Charlottenburg bekommt. Es wird seit dem Jahr 2017 vom Bundesamt für Bauwesen und Raumordnung (BBR) errichtet. Jetzt naht die Fertigstellung des hochspezialisierten Wissenschaftsbaues, in dem es unter anderem um die Forschung rund um sogenannte SQUIDs gehen wird – eine Spezialität der PTB, bei der sie seit Jahrzehnten in der Forschung eine internationale Spitzenstellung einnimmt. Auch das „neue Kelvin“ bekommt hier gewissermaßen eine Heimat.

An overview of the diverse research landscape of PTB as well as some particularly highlighted topics (for example, PTB research surrounding the International System of Units SI) you will find in the chapter Opens internal link in current windowResearch & Development). In addition, it is always worthwhile to look at the Opens internal link in current windowmain Homepage as well as the homepages of the respective Opens internal link in current windowDivisions. How reputable PTB is among researchers you can see at Opens internal link in current windowPTB in the World of Research. Furthermore, PTB has been – specifically its R&D component, in particular – evaluated repeatedly with excellent results. You can download the respective documents (which are in German only) in the right column as a pdf file.

Scientific publications

In the database Opens internal link in current windowPTB-Publica you can search for scientific publications by PTB staff members. Furthermore, some divisions maintain their own overview lists on the publications of their staff members. These you will find via the respective Opens internal link in current windowhomepages of the divisions.

Research collaborations
