Computational methods of quantum chemistry and relativistic effects in the electronic structure of heavy and superheavy elements
With an increase in the atomic number Z, a quantum description of the electronic structure of heavy elements and their chemical compounds can be achieved only in the relativistic approach. The report gives a general overview of methods of computational quantum chemistry in their development from the non-relativistic to relativistic limit. The results of applying these methods to describe a number of specific physical and chemical characteristics of systems containing the elements of the 6th and 7th periods of the Periodic Table are also considered.

Methods and Algorithms for Solving Resource Optimization Problems in Non-Stationary Distributed Heterogeneous Computing Environments
(based on the doctoral thesis)
The talk discusses the opportunities and challenges of mitigating uncertainty in cloud computing. The structure of uncertainties arising, in particular, from performance and bandwidth changes, virtualization, and elasticity, is analyzed. The uncertainty associated with workload properties, the dynamism of the execution context and the uncertainty related to such important aspects as privacy, security, and availability are also described.
Planning challenges for different scenarios of HPC, Grid and Cloud Infrastructures are addressed. Some theoretical and experimental results are provided, and static, dynamic and adaptive approaches are considered. The challenges of resource optimization in the presence of nonstationarity, ranging from resource heterogeneity handling, the dynamic behavior of the execution context, as well as the uncertainties associated with cloud parameters, are discussed.

*Method for programming calculations in a hybrid cloud by the example of pairwise processing of data array elements*
(based on the PhD thesis)
The report discusses the problem of the efficient use of a hybrid
cloud in the context of a method for developing algorithms in a form
that is convenient for execution on an arbitrary set of computing
resources. The method is based on the joint application of Cole’s
algorithmic skeletons and a variant of Hewitt’s actor model to describe
many-task computing. The proposed method is investigated by the example
of algorithms for pairwise processing of data arrays according to the
principle of a round-robin tournament. Computational experiments
demonstrate the effectiveness of software implementations of these
algorithms on various types of modern computer architectures that
represent hybrid cloud resources.

Title: *Measuring intact protons at the LHC: From the odderon discovery to the search for axion-like particles*
Abstract:
In the first part of the talk, we will describe the odderon discovery by the TOTEM and D0 experiments. The analysis compares the proton-antiproton elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV. The two data sets disagree at the 3.4 sigma level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering, leading to a combined significance larger than 5 sigma. In a second part of the talk, we will describe the perspective on the search for quartic anomalous couplings and axion-like particles using tagged protons in the final state, leading to sensitivities to beyond standard model physics that improve by 2 to 3 orders of magnitude on the coupling. We will finish by describing briefly the ultra fast silicon detectors for timing measurements as well as for medical and cosmic ray physics applications.

Constructive Study of Decompositions of Quantum Systems Into Subsystems
Any Hilbert space with composite dimension can be represented as a tensor product of smaller Hilbert spaces. This factorization allows one to decompose a quantum system into subsystems. We propose a model based on finite quantum mechanics for the constructive study of such decompositions and for the study of quantum correlations in the resulting multicomponent systems. To solve these problems, we develop and implement algorithms based on methods of computer algebra and computational group theory.

A source of ultracold neutrons slowed down by a magnetic or material UCN trap
V.V.Nesvizhevsky
Nuclear & Particle Physics Department, ILL, Grenoble, France
Ultracold neutrons (UCNs) are widely used in the physics of elementary particles and fundamental interactions, and can potentially be used in neutron scattering. However, most of these studies are limited by the available UCN densities and fluxes. One of the ways to increase them, as noted already in the first years of research with UCN, is to use peak fluxes in pulsed neutron sources, orders of magnitude higher than the average. In the present work, the concept of UCN sources is proposed, which makes it possible to implement this idea. We propose to produce very cold neutrons (VCN) in converters located in neutron sources and extract them with low losses. We propose a new way of focusing them in time, as well as their deceleration to UCN energies by an escaping decelerating material or magnetic trap. For both pulsed and permanent neutron sources, this method can provide high conversion efficiency of VCN to UCN.

Title: *Quantum Computing Using Multilevel Systems*
Abstract:
Quantum computers are computing devices that use quantum phenomena (such as quantum superposition and quantum entanglement) to solve problems. Quantum computing devices have the potential to outperform classical computers in a variety of tasks, such as cryptanalysis, complex system modeling, and machine learning. The presentation will provide an overview of various models of quantum computing, as well as the main applications of quantum computing devices. We will also consider a model of quantum computing using multilevel systems (qudits). The proposed model is based on a combination of several approaches. The first approach exploits the general relationship between the dimension of the qubits and their link topology, which is necessary for a scalable multi-qudit processor, where higher levels of qudits are used to replace auxiliary qubits. The second approach uses the decomposition of multi-level systems into a set of two-level systems. The application of the approach in current experiments with quantum information processing systems is discussed. The questions of the analysis of quantum computing devices in the context of the theory of open quantum systems will also be touched upon.

Title: Measurement of the radiation environment of the ATLAS cavern in 2017–2018 with semiconductor pixel ATLAS-GaAsPix detectors
Abstract:
A network of ten semiconductor Timepix detectors with GaAs:Cr sensors was installed in the ATLAS cavern at CERN’s LHC during the shutdown periods 2015–2016 and 2016–2017 in the framework of a cooperation between ATLAS and the Medipix2 Collaboration. The purpose was to augment the existing system of measuring and characterising the radiation environment in the ATLAS cavern that is based on ATLAS-TPX devices with pixelated silicon sensors. The detectors were in continuous operation during 13 TeV proton-proton collisions in 2017–2018. Data were recorded during proton-proton bunch crossings, and during times without bunch crossings (LHC physics runs) as well as between the physics runs. The detectors recorded all interactions of charge particles, neutrons and photons in GaAs sensors, in which the signal was higher than 6.5 keV in individual pixels. This made it possible to register clusters (tracks) of individual radiation particles interacting in the detectors sensors. During the LHC beam-beam collisions the radiation background contains particles produced at the interaction point which punch through the ATLAS detector. In the periods without beam-beam collisions, there were photons and electrons resulting from radioactivity induced during previous collisions in GaAs detectors and in surrounding construction materials, namely by neutrons. The ATLAS-GaAsPix Network measured overall level of particle radiation, the ratio between neutral and charged particles as well as neutron flux distribution in the cavern by measuring a level of induced radioactivity in the sensor materials.

Supercomputing and Nuclear Analytical Methods for Air Pollution Management
1.Vladislav Svozilík*
Mathematical Modelling of Air Pollution – Results Verification and Future Perspective
A substantial part of the seminar is devoted to the results of Vladislav Svozilik’s Ph.D. thesis on the topic “Verification of Mathematical Air Pollution Modelling Results by the ADMoSS Model Using UAS Measurement and Biomonitoring”. Knowing the relationship between pollution sources and air pollution concentrations is crucial. Mathematical modelling is a suitable method for the assessment of this relationship. The Analytical Dispersion Modelling Supercomputer System (ADMoSS) is used for air pollution modelling in large areas. Not all pollution sources can be included in the modelling itself, and other uncertainties arise during the simplification of reality. Therefore, calibration by standard air pollution monitoring was included in ADMoSS. Consequently, alternative monitoring methods are needed for model verification. The verification is performed using the results of two special monitoring methods. The first one is a method for measuring air pollution by unmanned airships, and the second one is biomonitoring of air pollution using mosses. The results show that flight measurements using an unmanned airship are suitable for capturing dynamic phenomena, but not verifying a model that reflects a long-term situation in a large area. On the contrary, moss biomonitoring is a suitable method for evaluating modelling results, as well as for identifying specific chemical elements whose distribution coincides with the mathematical model.
2. Petr Jančík*
IT for air quality management – status and perspectives of further cooperation with JINR.
In this case, the broad title encompasses the measurement and mathematical modeling of air pollution, geoinformation technologies for analyzing their results, as well as the preparation and implementation of modeling on parallel supercomputer clusters. Over the past few years, my team and I have been researching and refining mathematical models, expanding the amount of processed input data using powerful supercomputers and verifying model calculations via special monitoring by nuclear analytical methods, namely, NAA of bryophytes, unmanned aerial vehicles and a robotic automatic sampler placed on filters of a former mining tower in the area of interest. We have created a model of air pollution relations in a large area between the Czech Republic, Poland and Slovakia, which is called Tritia. For this area, we have developed an Air Quality Management System that uses the results of retrospective and perspective modeling over a long period of time (from 2006 to 2040). Researchers from the above countries and JINR have participated in all these works.

Methods and software to decrease the number of errors in the code by reducing the programmer’s participation
(based on the PhD thesis)
Projects to create and develop the digital economy are implemented in Russia and many other countries. People can make mistakes in any program. Three new methods for reducing software errors are considered.
Currently, almost all programming languages are algorithmic. A non-algorithmic Problem Description Language (PDL) is presented. Problem descriptions are created in this language, and then the translator converts them into a text of a high-level algorithmic language. The use of PDL allows one to reduce the programmer’s participation in writing programs. A new method for defining the context of words and documents is described. This method can be applied to the computer analysis of program descriptions and other natural language texts. A bank of algorithm descriptions specially created for the PDL -> Perl translator is proposed. It is a database of software modules that can be used by both humans and computers. The PDL language is tested with the PDL -> Perl translator.

“Measurements of WH and ZH production in the H→b anti-b decay channel in pp collisions at 13 TeV with the ATLAS detector
(on results obtained by the JINR team at the ATLAS at the LHC)”
Abstract:
Measurements of the Standard Model Higgs boson decaying into a b anti-b
pair and produced in association with a W or Z boson decaying into
leptons, using proton-proton collision data collected between 2015 and
2018 by the ATLAS detector, will be presented. The measurements use
collisions produced by the Large Hadron Collider at a centre-of-mass
energy of √s=13 TeV, corresponding to an integrated luminosity of 139
1/fb. The production of a Higgs boson in association with a W or Z boson
is established with observed (expected) significances of 4.0 (4.1) and
5.3 (5.1) standard deviations, respectively. Cross-sections of
associated production of a Higgs boson decaying into bottom quark pairs
with an electroweak gauge boson, W or Z, decaying into leptons are
measured as a function of the gauge boson transverse momentum in
kinematic fiducial volumes. The cross-section measurements are all
consistent with the Standard Model expectations, and the total
uncertainties vary from 30% in the high gauge boson transverse momentum
regions to 85% in the low regions. Limits are subsequently set on the
parameters of an effective Lagrangian sensitive to modifications of the
WH and ZH processes as well as the Higgs boson decay into b anti-b.

Offline Software and Computing for the SPD experiment
The SPD (Spin Physics Detector) is a planned spin physics experiment in the second interaction point of the NICA collider that is under construction at JINR. The main goal of the experiment is the test of basic of the QCD via the study of the polarized structure of the nucleon and spin-related phenomena in the collision of longitudinally and transversely polarized protons and deuterons at the center-of-mass energy up to 27 GeV and luminosity up to 10^32 cm^(-2) s^(-1). The data rate at the maximum design luminosity is expected to reach 20 GB/s. Current approaches to SPD computing and offline software will be presented. The plan of the computing and software R&D in the scope of the SPD TDR preparation will be discussed.
