Guglielmo Lockhart arrives with ERC Starting Grant

New member of the Physikalisches Institut and Bethe Center doing research in mathematical physics

Meeting of the German institutes in the ATLAS-Collaboration in Bonn

The Physikalisches Institut is the host of this year's meeting of the German institutes in the ATLAS-Collaboration at the Large Hadron Collider. From 19th to 22nd of September 2023, the focus of the physicists are the operations and data taking of the ATLAS experiment, the analysis of the data, and the coming upgrades of the detector for future data taking periods.

New World Record: Thinnest Ever Pixel Detector Installed

The Belle II cooperation project at the Japanese research center KEK is helping researchers from all over the world to hunt for new phenomena in particle physics. The international experiment has now reached a major milestone after a team successfully installed a new pixel detector in its final location in Japan. The size of a soda can, the detector was developed in order to make out the signals coming from certain types of particle decays, that can shed light on the origin of the matter-antimatter asymmetry that has been observed in the universe. The installation ran without a hitch and is a key milestone in the evolution of the experiment and German-Japanese research collaboration.

Effect in the quantum world

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics. The publication has now been released in the journal Nature Physics.

PhenoDay at the Bethe Center

A one-day meeting on particle phenomenology was organized by Herbi Dreiner's group in Bonn together with groups from Aachen, Heidelberg, Nijmegen and U. Amsterdam.

ERC Proof of Concept Grant for Prof. Dr. Simon Stellmer

Prof. Dr. Simon Stellmer has been awarded a Proof of Concept Grant by the European Research Council (ERC) as part of a program designed to help researchers translate their ideas from previous ERC projects into commercial applications. The grant is endowed with €150,000.

"Planetamos" on tour for the first time

From 22 - 25 March, the Physics Show of the University of Bonn made a guest appearance at the University of Tübingen.

New ATLAS result weighs in on the W boson

The W boson is the mediator particle of the electroweak force. Discovered in the 1980s at CERN, its properties remain challenging to measure within the Standard Model of particle physics. Members of the research group of Prof. Dr. Klaus Desch and Priv.-Doz. Philip Bechtle as well as of the research group of Prof. Dr. Ian Brock are involved in the latest and improved W boson mass measurement presented by ATLAS at the Moriond electroweak conference.
