Alexei Starobinsky, Professor in Faculty of Physics, Elected Foreign Associate at U.S. National Academy of Sciences

Alexei Starobinsky, Professor in Faculty of Physics, Elected Foreign Associate at U.S. National Academy of Sciences

Alexei Starobinsky, Professor in the HSE Faculty of Physics, has been elected Foreign Associate at the U.S. National Academy of Sciences. Previously, he has served as an elected member of the National Academy of Sciences of Germany (Leopoldina), the Norwegian Academy of Science and Letters, and two Indian academies – the Indian National Science Academy (New Delhi) and the National Academy of Sciences (Allahabad).

Professor Starobinsky’s research interests include classical and quantum theories of gravity, cosmology, and relativistic astrophysics. He authored the first books on the inflation theory (1979, 1980), which is the leading cosmology theory today and describes the early universe before the Hot Big Bang stage. Together with Andrei Linde and Alan Guth, he is considered a founder of this theory; for their achievement, in 2014, they were jointly awarded the Kavli Prize, a leading international award in astrophysics. He is also the recipient of one of the most prestigious awards in cosmology, the Gruber Prize in Cosmology (2013), as well as several other medals and awards, including the Andrei Sakharov golden medal awarded by the Russian Academy of Sciences (2016).

Professor Starobinsky’s scholarly achievements also include the calculation of the number of created particles and the average tensor in momentum energy of quantum fields in homogeneous anisotropic cosmological models (1971, co-authored with Y.B. Zeldovich). He developed the hypothesis suggested by Zeldovich in 1971 and proved that rotating black holes must generate and radiate particles (1973), which was a precursor of Stephen Hawking’s theory that all black holes, not only rotating ones, radiate particles (1974). Together with Y.N, Pariiski et al, Professor Starobinsky also discovered angular fluctuations of the temperature of cosmic microwave background radiation using a RATAN-600 radio telescope (1992).

Alexei Starobinsky is Chief Research Fellow at the RAS Landau Institute for Theoretical Physics and a member of the editorial board at ten leading academic journals in the areas of his research interests.

The U.S. National Academy of Sciences is the most authoritative public academic organization in the United States. It was founded in 1863 by the U.S. Congress, and its founding act was signed by President Abraham Lincoln. The academy aims to serve as an expert community that helps the country and the public in the most complicated issues related to science. Academy members work on a pro bono basis.

Today, the U.S. National Academy of Sciences counts about 2,350 members and over 450 foreign associates. Approximately 200 Nobel Prize laureates serve as members. New members are elected for life by current members in a ballot vote. Being elected as a foreign associate of the Academy is one of the most significant acknowledgements of a person’s input on global science.

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.

Russian Physicists Determine Indices Enabling Prediction of Laser Behaviour

Russian scientists, including researchers at HSE University, examined the features of fibre laser generation and identified universal critical indices for calculating their characteristics and operating regimes. The study findings will help predict and optimise laser parameters for high-speed communication systems, spectroscopy, and other areas of optical technology. The paper has been published in Optics & Laser Technology.

HSE Scientists Have Developed a New Model of Electric Double Layer

This new model accounts for a wide range of ion-electrode interactions and predicts a device's ability to store electric charge. The model's theoretical predictions align with the experimental results. Data on the behaviour of the electric double layer (EDL) can aid in the development of more efficient supercapacitors for portable electronics and electric vehicles. The study has been published in ChemPhysChem

Roman Gaydukov, Associate Professor at the MIEM HSE School of Applied Mathematics, has modelled the fluid flow around a rotating disk with small surface irregularities. His solution allows for predicting fluid flow behaviour without the need for powerful supercomputers. The results have been published in Russian Journal of Mathematical Physics.

Physicists from Russia and Brazil Unveil Mystery behind Complex Superconductor Patterns

Scientists at HSE MIEM and MIPT have demonstrated that highly complex spatial structures, similar to the intricate patterns found in nature, can emerge in superconductors. Mathematically, these patterns are described using the Ginzburg–Landau equation at a specific combination of parameters known as the Bogomolny point. The paper has been published in the Journal of Physics: Condensed Matter.

An international team of researchers, including scientists at HSE University and Moscow Pedagogical State University (MPGU), has developed a novel photodetector composed of a thin superconducting film, capable of detecting weak terahertz (THz) radiation. This discovery holds promise for studying objects in space, developing wireless broadband communication systems, and making advancements in spectroscopy. The study has been published in Nano Letters.

Operation of Cellular Networks Found Similar to Bacteria Growth in Petri Dish

Scientists at the HSE Laboratory for Computational Physics have developed a new model for analysing communication networks that can significantly enhance the speed of mobile communications. To achieve this, the researchers used computational physics methods and phase transition models. It turns out that the functioning of cellular networks is in many ways similar to the growth of surfaces in physics. The study was performed using the HPC cHARISMa cluster at HSE University. The study findings have been published in Frontiers in Physics.

The team from the Kingdom made their first visit to Russia to receive their final training at the HSE Faculty of Physics.

'I've Always Been Keen to Engage in Experiments and Operate Scientific Instruments'

During his early years at university, physicist Ivan Makhov worried that he might be dismissed, but today he is heading a study supported by a grant from the Russian Science Foundation. In this interview with the HSE Young Scientists project, he shares his work experience using a closed-loop cryostat, his dream of conversing with Einstein, and favourite location in his hometown of St Petersburg.

‘Two Interdisciplinary Research Centres Can Create New Synergy between Themselves’

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.
