Physicists at HSE University and FIAN Discover Way to 'Photograph' Sound for Testing Materials Used in 6G Communications
Researchers at HSE University, in collaboration with colleagues from the Lebedev Physical Institute of the Russian Academy of Sciences (FIAN), have developed a method for rapidly determining how firmly a film is bonded to a substrate. This is important for the creation of ultrahigh-frequency acoustic filters, which are key components of next-generation 5G and 6G communications. For the first time, researchers have succeeded in measuring the lateral rigidity of the bond between a two-dimensional material film and a substrate in this way. The study results have been published in Applied Physics Letters.
Physicists at HSE University Reveal How Vortices Behave in Two-Dimensional Turbulence
Researchers from the Landau Institute for Theoretical Physics of the Russian Academy of Sciences and the HSE University's Faculty of Physics have discovered how external forces affect the behaviour of turbulent flows. The scientists showed that even a small external torque can stabilise the system and extend the lifetime of large vortices. These findings may improve the accuracy of models of atmospheric and oceanic circulation. The paper has been published in Physics of Fluids.
First Successful Attempt in 55 years: Physicists in Russia and Germany Confirm 1969 Experiment Results
A team of researchers, with the participation of physicists from HSE University, replicated the 1969 experiment on superconductivity and its properties. The scientists induced superconductivity by deliberately deteriorating the interfaces between the layers of superconductors and ferromagnets in the system, resulting in better performance of spin valves compared to the classical version, where the interfaces between the layers are ideal. This approach could lead to the development of more efficient devices for data storage and computing. The study findings have been published in the Beilstein Journal of Nanotechnology.
