The main goal of this study is to apply quantum field theory methods to determine the conditions of the Early Universe development, and to investigate the processes at the LHC, RHIC and other modern particle colliders. The goal also includes development of theoretical and computational methods of investigation of excited and ionized molecular states, investigation of thermodynamical stability in real-life and lattice systems, study of magnetic field states in interactions with emitting systems. In this study, we utilize quantum-field theory approach, quantum optics methods, Bogolyubov's reduced description approach, and Monte Carlo modelling. Based on the ATLAS and CMS data, we derive new bounds for Z' couplings to leptons and first-generation quarks. It is shown that in the O(4) model there is no symmetry breaking at coupling values less than 10-3, but the phase transition is observed at couplings in range of 10-3 - 10-1. We construct and analyze a large number of beta functions in lattice QCD, and propose a fitting function for lattice beta function. Also, we investigate supercritical properties for a series of statistical models and determine a connection between thermodynamic stability and anharmonic crystal lattice oscillations. We determine a full set of parameters of a system and a packet that describe all tunneling properties. Main dynamic characteristics of packet tunneling through a quantum dot and a tunneling diode are calculated. The results obtained in this investigation are new and impose a significant contribution to the elementary particles theory, field theory under extreme external conditions, thermodynamical stability theory, theory of electromagnetic processes in media, Bose gas kinetics in presence of condensate and the reduced description method for non-equilibrium processes. The scientific accuracy and the high quality of this study are recognized at international conferences and confirmed by the referees of World'd top scientific journals that publish the results of these researches. The results can be utilized by the top research and development institutions in Ukraine and in the world: ITP NAS, Kyiv, NSC KIPT, Kharkiv, ICMP, Lviv, CERN (Switzerland), ICTP (Italy), DESY (Germany), University of Brussels (Belgium), MIT (USA), Florida State University (USA) Boston College (USA), Theorie-Modelisation-Simulation Lab, CNRS (France). The results of the conducted researches are applied for development and teaching of the following courses: "Quantum Electrodynamics ", "Continuous Medium Electrodynamics " etc. Product Description popup.authors Іванов Микита Анатолійович Галдіна Олександра Миколаївна Гулов Олексій Володимирович Демчик Вадим Ігорович Кожушко Андрій Андрійович Соколовський Олександр Йосипович Ступка Антон Анатолійович popup.nrat_date 2020-04-02 Close
