Cluster of ExcellenceQuantum Universe

In the Shielded Experimental Hall (SHELL) at the University of Hamburg, an international research collaboration involving the Cluster of Excellence Quantum Universe is developing the MADMAX experiment to detect axions. The particles are considered promising candidates for dark matter and could solve a mystery surrounding...

Researchers at the University of Hamburg and DESY have found evidence of the elusive toponium. With this discovery, the fundamental structure of matter could be deciphered in even greater detail.

Yesterday, the International Congress of Basic Science (ICBS) in Beijing presented Professors Mathias Schacht and Paul Wedrich with the prestigious Frontiers of Science Award. The scientists from the Department of Mathematics of the Faculty of Mathematics, Informatics and Natural Sciences at the University of Hamburg were...

In the summer of 2023, several pulsar timing array collaborations found the first evidence for the existence of a gravitational wave background, a constant hum of gravitational waves permeating our universe. This evidence opens a new window to investigate the sources of those gravitational waves. In a recent paper...

A Marie Skłodowska-Curie Fellowship will start in February 2026 in the group of Prof. Dr. Konstantinos Nikolopoulos, experimental physicist at Universität Hamburg—University of Excellence. Funding of around 200,000 euros will be provided for the two-year research project neutrinoSPHERE.

Detectors at future colliders promise beautiful highly-granular images of particle collisions. To make use of this data, simulating a vast number of events with high precision is necessary. At the Cluster of Excellence Quantum Universe, bleeding edge Generative Machine Learning (ML) models that meet the strict requirements...

It is quite common for research equipment to end up in display cases and exhibition rooms: discarded prototypes, particularly attractive particle detectors or innovative new developments help to explain science and are technological witnesses to the times. However, it is rather rare for exhibits to be dusted off and moved...

Do we bathe in dark matter? How do we tap into the mysteries of a 5,000-year-old letter? Is climate protection a private matter or a national goal? And does the language I use shape my identity? At "Science on Tap", researchers from the University of Hamburg and DESY answer fascinating and urgent questions.

The postulation of an axion poses an elegant solution to the strong CP problem of the Standard Model. The construction of such a solution could be jeopardized by new sources of CP violation at high energies. Using an effective field theory approach to describe these new sources of CP violation, a group of Quantum Universe...
