HSE MIEM Professor Elected Fellow of American Physical Society
The American Physical Society (APS) has recognised HSE MIEM Professor Lev Shchur for his innovative use of computer simulations and the development of superior random number generators for their use in statistical physics. Professor Shchur is the only academic working in Russia to be selected as APS Fellow in 2017.
Founded in 1899 by physicists from Columbia University, the American Physical Society is one of the oldest academic communities in the world. The society includes 14 divisions and nine thematic groups representing all key areas of modern-day physics.
Lev Shchur’s academic interests lie at the interface of theoretical physics and computer software. He is a leading researcher with the Landau Institute for Theoretical Physics in Chernogolovka, Russia. At MIEM, Professor Shchur heads the Joint Department with RAS Dorodnicyn Computing Centre and teaches courses on distributed computing and parallel programming.
Professor Shchur is also the author of more than 140 works that have each made a significant contribution to contemporary science:
- The angle of transversal homoclinic intersection in Yang-Mills equations was numerically determined, which though the help of the computer has proven the non-integrability of Yang-Mills fields.
- In a work co-authored with S. Manakov, stochasticity was found in the scattering of vortex pairs, which is evidence of the non-integrability of two-dimensional hydrodynamic equations.
- A paper co-authored with A. Talapov showed how specialised computers were built to research spin models. A correlation function was numerically obtained for the first time ever, and it was shown that impurities do not change the universality class. Instead they simply modify the correlation length with logarithmic corrections.
- Together with P. Bueter and B. Barash, numerical assessments were created on universal combinations of critical amplitudes in the two-dimensional Potts model, while the precise reduction of logarithmic corrections was shown analytically in the universal relations of critical amplitudes.
- A work co-authored with H. Blöte explained the undesirable correlation between the cluster Monte Carlo method and a random number generator on shift registers. A theory was developed on such correlations.
- A new approach was proposed towards the development of pseudo-random number generators based on the mapping torus and hidden variables. Together with L. Barash, a library of effective random number generators was developed.
- In a work co-authored with M. Novotny, a classification system was proposed for parallel discrete event simulation (PDES) algorithms using the analogy of the evolution of the PDES time horizon together with the evolution of the surface profile in Kardar–Parisi–Zhang equations.
LHCb (Large Hadron Collider beauty) collaboration, one of the LHC (Large Hadron Collider) experiments, reported that their detector has identified particles that have not previously been detected in physics experimentally – excited omega baryons (Ω-b). Just several years ago, detecting such particles in LHC was believed to be next to impossible. Among proton particles, the excited ‘charmed omegas’ were preselected by an algorithm created by staff from the HSE Laboratory of Methods for Big Data Analysis and Yandex LLC. IQ.HSE talked to Denis Derkach and Fedor Ratnikov about their collaboration’s ‘fresh catch’ and about the point of ‘fishing’ on LHCb in general.
Alexey Starobinsky, a professor of physics at HSE University and a fellow at the Landau Institute for Theoretical Physics at the Russian Academy of Science, has been awarded the Dirac Medal of the ICTP, a prestigious prize awarded annually by the Abdus Salam International Center for Theoretical Physics. HSE News Service spoke with the laureate about his path to international recognition, his students, and the award.
Students in the Faculty of Physics, one of the newest departments at HSE, will find a homey atmosphere, understanding teachers, and the opportunity to engage in science from the first year of studies. Physics students Arslan Galiullin (2nd year) and Sofia Lopatina (1st year) will be our guides for this instalment of the Open House project.
The HSE University competition committee has announced the winners of an international competition for new physics laboratory proposals. Two proposed projects were selected: the Laboratory of van der Waals Heterostructures, headed by Davit Ghazaryan, and the Laboratory of Nanophotonics and Functional Materials, headed by Andrey Krasavin.
A team of researchers from Germany and Russia have demonstrated that long contraction of muscles in one hand increases involuntary reaction of the other one. Meanwhile, the time between muscle contractions in both hands decreases. The results of the study have been published in the paper ‘Inverse relationshipbetween amplitude and latency of physiological mirror activity during repetitive isometric contractions’ in Neuroscience.
The results of recent study conducted by the NASA Lunar Reconnaissance Orbiter, the agency’s automatic interplanetary station, show the existence of a ‘permafrost’ near the poles of the Moon with a relatively high content of water ice (up to 5% by weight). It is believed that water ice could supply a life support system for the future Russian Lunar Station and that it could also produce hydrogen-oxygen fuel for flights into deep space.
At the general meeting of the Russian Academy of Sciences (RAS), held on April 23, research by Alexander Kostinskiy, Vladimir Rakov and Mikhail Andreev conducted in collaboration with their colleagues from academic institutes on the modeling and development of lightning was acknowledged as one of the most significant Russian scientific achievement in 2018.
Researchers from HSE University and Yandex, as part of the LHCb collaboration at CERN, have been the first to discover CP violation in charm meson decays.
Scientists from HSE University and Yandex have developed a method that accelerates the simulation of processes at the Large Hadron Collider (LHC). The research findings were published in Nuclear Instruments and Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment.
Physicists from the Higher School of Economics and Space Research Institute have identified a mechanism explaining the appearance of two dusty plasma clouds resulting from a meteoroid that impacted the surface of the Moon. The study was published in JETP Letters.
