Explore a 40-minute scientific seminar lecture from the Bogolyubov Institute for Theoretical Physics that examines the scalar model of interacting boson systems at high temperatures. Delivered as part of the scientific seminar series in memory of Petro Ivanovich Fomin on "Quantum Field Theory and Cosmology," this theoretical physics presentation investigates fundamental concepts in quantum mechanics and statistical physics. Learn about the behavior of bosonic particles and their interactions in extreme temperature conditions through detailed mathematical and theoretical analysis.
