What is a perfect fluid? It is a theoretical model of a fluid that allows us to assume that the fluid is not viscous, that it does not conduct heat, that it is incompressible and does not create vortices. It is therefore an approximation of reality that simplifies theoretical predictions of fluid flows. For the first time, an international team has experimentally demonstrated this same behaviour for light immersed in a medium of low refractive index.

On 21 and 22 September 2023, for the 4th year running, Belgian researchers came together for the bePOM conference. The format was original, with a virtual day and a hybrid day combining virtual and face-to-face sessions. A great success, and a Belgian network that is growing from strength to strength.

Two researchers from the University of Namur's Department of Physics, Professor Michaël Lobet and his PhD student Adrien Debacq, are taking a close look at a subject that fascinates the scientific community : superradiance in media with a refractive index close to zero. In an article published this summer in Nature's prestigious journal Light: science & applications, in collaboration with Harvard University (USA), Michigan Technological University (MTU) and Sparrow Quantum, they contribute to the development of quantum computing.

During the Japanese Emperor’s state visit to Belgium, two professors from the University of Namur had the opportunity to represent their institution at two highlights of the official program. Isabelle Parmentier and Alexandre Mauroy reflect on an experience they won’t soon forget.
