Conferences

Varied programme, bright reports and discussions

On 21 - 25 October, the 11th International Conference "Mathematical Modeling and Computational Physics" (MMCP 2024) was held at Yerevan State University (YSU, Armenia). The event was dedicated to the 80th anniversary of the outstanding scientist in the field of elementary particle physics, theoretical and mathematical physics, Director of JINR (2006-2010) Academician Alexey Sisakyan (14.10.1944-01.05.2010). The Conference was organized by the Joint Institute for Nuclear Research, A.I.Alikhanyan National Science Laboratory (ANSL) and the Institute for Informatics and Automation Problems of the National Academy of Sciences of the Republic of Armenia (IIAP NAS RA).

Over 150 scientists and specialists from 18 countries and from a large number of Russian research centres and universities took part in the Conference: HSE, Dubna State University, IMPB RAS, IMPB KIAM RAS, MADI, NRC Kurchatov Institute, NINP MSU, PNPI NRC KI, RUDN, SPbU, Skoltech, ITMO University, SICP RAS, Financial University under the Government of the Russian Federation, LPI, Valiev Institute of Physics and Technology RAS.

Vice-Rector for Research at Yerevan State University Rafael Barkhudaryan opened the plenary session with a report on the YSU scientific programme.

One of the traditional areas of computational mathematics and computational physics covered at MMCP Conferences is the area related to the development of techniques and tools for simulating complex physical systems. A number of interesting reports were delivered in these areas. Hassan Safohi (University of Alberta, Canada) spoke about the application of non-standard techniques of numerical integration using extrapolation and asymptotic expansion in calculating complex integrals. Progress achieved in the framework of the Bayesian approach to calculating Riemann integrals using automatic adaptive quadrature was the topic of the report by Gheorghe Adam (MLIT). Khachatur Khachatryan (YSU) spoke about classical and weakened solutions of the Cauchy problem for a class of nonlinear parabolic equations. The report by Victor Braguta (BLTP) was dedicated to the impact of relativistic rotation on the properties of quantum chromodynamics. A number of sectional reports were dedicated to the techniques of computational physics concerning the techniques of quantum field theory as applied to stochastic nonlinear dynamics and critical phenomena.

A large group of reports was dedicated to techniques and numerical algorithms in the field of high energy physics (HEP), including techniques of data processing and analysis in mega-science projects. Andrey Arbuzov (BLTP) presented the current state of the SANC computer system developed for accurate calculations of event distributions concerning various decay processes and interactions of elementary particles in HEP. Vladimir Karzhavin (VBLHEP) highlighted JINR's participation in the CMS experiment (LHC): in the development and modernization of detectors, data accumulation and analysis, software development, reliable operation of Tier1/Tier2 grid sites for data storage and processing. Vladimir Korenkov (MLIT) gave an overview of the techniques and technologies for the development of distributed computing systems for storing, processing and analyzing experimental data from large scientific facilities (LHC, NICA, neutrino programme, others) using the example of the JINR Multifunctional Information and Computing Complex. Nikolay Voytishin (MLIT) spoke about techniques of event reconstruction in today's experiments of HEP. Gennady Ososkov's (MLIT) report focused on the task of recognizing the trajectories of charged particles based on machine learning techniques. Alexey Zhemchugov (DLNP) dedicated his reports to computing for the experiments of the mega-science project NICA to SPD, Konstantin Gertsenberger and Oleg Rogachevsky (VBLHEP) - to BM@N and MPD.

Reports on distributed and parallel computing, as well as on artificial intelligence were delivered at the Conference. In his report, Artashes Mirzoyan (IIAP NAS RA) presented an overview of the Aznavour supercomputer as a national supercomputer centre in Yerevan, providing computing power for meeting complex tasks in various disciplines. In turn, Maxim Zuev (MLIT) spoke about the JINR heterogeneous HybriLIT platform that includes a training and testing ground and the Govorun supercomputer, as well as the tasks that are calculated on its resources. The participants of the Conference listened with great interest to the report of the leading Russian specialist in system programming Academician of the Russian Academy of Sciences Harutyun Avetisyan (ISP RAS) "Prospects for the development of system programming and cybersecurity". Anonymous computing for reliable authentication in self-organizing swarms of unmanned aerial vehicles was the topic of the report by Yeghisabet Alaverdyan (IIAP NAS RA).

A number of plenary reports were dedicated to the development of mathematical techniques in life sciences. Viktor Lakhno (IMPB RAS, Pushchino, Russia) spoke about the basics of nanobioelectronics and its potential applications and Alexander Bugay (LRB) presented an overview of the hierarchy of biophysical prototypes for studying complex DNA damage and cell survival after exposure of ionizing radiation with different properties.

The techniques and algorithms of quantum computing and quantum information processing were the topics of several plenary reports. The recognized world classic in the field of quantum computing Christian Kalude (New Zealand) presented a report in which he explained the superiority of quantum computing over traditional ones. The report of Vladimir Melezhik (BLTP) was dedicated to the quantum-semiclassical technique for quantitative analysis of various small-particle quantum problems in atomic and nuclear physics. Armen Allakhverdyan (ANSL) spoke about dissipative search in an unstructured database.

The Conference included a large number of interesting reports, accompanied by wide and insightful discussions. In total, 21 plenary and over 110 sectional reports were given.

The scientific programme of the Conference was accompanied by a rich cultural programme that allowed the participants to explore the picturesque places of Armenia during excursions, as well as to visit the exhibition at YSU dedicated to the 80th anniversary of the birth of Academician A.Sisakyan.

On 25 October, the Conference hall of Yerevan State University hosted public lectures by the staff of the Joint Institute for students and teachers of the Institute of Physics of Yerevan State University, organized by the JINR Information Centre at Yerevan State University - ANSL. Sergey Merts (VBLHEP) gave a lecture on "NICA: "Back to the future". Andrey Arbuzov (BLTP) gave a talk on "Secrets of cosmology". Maria Savina (BLTP) spoke about the search for new physics. Sergey Shmatov (MLIT) delivered a lecture on "Why do physicists need computers?".
