Learn about Davydov's solitons and their crucial role in biological processes through a 46-minute physics lecture delivered at the Bogolyubov Institute for Theoretical Physics. Explore fundamental concepts including soliton wave functions, Coulomb repulsion, and one-dimensional systems. Delve into advanced topics such as hybrid entangled solitons, their lifetimes, and behavior in low-dimensional systems. Examine practical applications through discussions of phase diagrams, structure geometry, and kinetics of delayed luminescence. Discover how solitons function in atmospheric conditions and zigzag nanotubes, concluding with an interactive Q&A session. Master theoretical physics concepts that bridge the gap between mathematical models and biological phenomena.
