International research team cracks a hard physics problem

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems. However, these methods reach their limits when so-called sign oscillations occur. This problem has now been solved by an international team of researchers from Germany, Turkey, the USA, China, South Korea and France using the new method of wavefunction matching. As an example, the masses and radii of all nuclei up to mass number 50 were calculated using this method. The results agree with the measurements, the researchers now report in the journal “Nature”.

Prof. Klaus Desch started the "Kinderuni" in Summer Term 2024

"Unraveling the puzzle"- this is the motto under which the University of Bonn opened the summer-term Kinderuni on Monday, April 15. In his lecture, Prof. Klaus Desch from the Physikalisches Institut made the invisible visible!

The "Physik Lernzentrum" opens its doors

This semester, the time has finally come: four days a week, experienced tutors are available in the foyer of the Wolfgang Paul Lecture Hall to help first- and second-semester students with exercises in "Experimentalphysik II" and "Theoretische Physik I" or with questions about the content of these lectures.

BCGS poster session 2024: Program now available!

19 April 2024, Bonn Wolfgang-Paul Lecture Hall, 13.15 - 16.30 h

Women* in Physics Bonn: Events in Summer Semester 2024

"Women* in Physics Bonn" is a community of women* that meet monthly to share their experiences and foster connections among women* in physics. Their goal is to network in a relaxed and friendly environment over coffee and cake, and to engage in work-related discussions with the other participants - from Master's students up to postdocs.

Matthias Schott starts a new research group at the Physikalisches Institut

The new research group of Matthias Schott works on questions of experimental particle physics, in particular on precision measurements of electroweak gauge bosons, studies of non-perturbative effects of QCD, and the search for axion-like particles.

NRW Minister Ina Brandes visits the ELSA electron accelerator

Ina Brandes, Minister for Culture and Science of the State of North Rhine-Westphalia, has visited the electron accelerator "ELSA" on the Poppelsdorf campus of the University of Bonn. The large-scale device has been reliably delivering the latest findings for research into the building blocks of matter for over three decades. It is part of a 70-year tradition of Nobel Prize-winning accelerator research at the University of Bonn.

Neue Methode misst die 3D-Position einzelner Atome

Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom – i.e., the distance between the atom and the microscope objective – is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image. This method – developed by the University of Bonn and University of Bristol – is based on an ingenious physical principle. The study was recently published in the specialist journal Physical Review A.
