Researchers from HSE University in Nizhny Novgorod have shown that a neural network can reconstruct the dynamics of a brain neuron model using just a single set of measurements, such as recordings of its electrical activity. The developed neural network was trained to reconstruct the system's full dynamics and predict its behaviour under changing conditions. This method enables the investigation of complex biological processes, even when not all necessary measurements are available. The study has been published in Chaos, Solitons & Fractals.

Physicists from the Institute of Spectroscopy of the Russian Academy of Sciences and HSE University have successfully trapped rubidium-87 atoms for over four seconds. Their method can help improve the accuracy of quantum sensors, where both the number of trapped atoms and the trapping time are crucial. Such quantum systems are used to study dark matter, refine navigation systems, and aid in mineral exploration. The study findings have been published in the Journal of Experimental and Theoretical Physics Letters.

Researchers at HSE University and MIPT have investigated how the composition of electrons in a superconductor influences the emergence of intertype superconductivity—a unique state in which superconductors display unusual properties. It was previously believed that intertype superconductivity occurs only in materials with minimal impurities. However, the scientists discovered that the region of intertype superconductivity not only persists but can also expand in materials with a high concentration of impurities and defects. In the future, these superconductors could contribute to the development of highly sensitive sensors and detectors. The study has been published in Frontiers of Physics.

In mid-June 2024, HSE University and the Joint Institute for Nuclear Research in Dubna held a joint working meeting. This meeting was the first under an agreement signed by the research centres in 2024, when HSE University and JINR agreed to jointly participate in experiments of the NICA megascience project, as well as interact in the field of theoretical and mathematical physics, information technology, and personnel training. These issues were the focus of the first working meeting. Details are in the JINR report.

Researchers from HSE, MIPT, and the Russian Academy of Sciences Institute of Solid State Physics, jointly with colleagues from the UK, Switzerland, and China, have conducted a study on the characteristics of thin films composed of platinum and niobium. Both the experiments and the theoretical calculations have confirmed that when in contact with a superconductor, platinum exhibits a spin, creating a potential for its effective use for data transmission. Platinum atoms have no magnetic moment, paving the way for the development of even smaller chips utilising this novel structure compared to conventional spintronics. The paper has been published in Nature Communications.

On October 10, 2016, the Faculty of Physics was created at HSE University. It was the university’s first natural science faculty. Its first master’s students graduated in 2019, its first bachelor’s students completed their studies in 2021, and the first doctoral students will do the same in 2023 after beginning their bachelor’s studies in 2017. In his interview, Mikhail Trunin, Dean of HSE University’s Faculty of Physics, talks about the Kapitsa educational system implemented at the faculty, the results that have been achieved in seven years of work, and what is still missing.
