Wave Turbulence and Loop Diagrams in Quantum Field Theory

Explore a physics seminar that delves into wave turbulence and its connection to quantum field theories through loop diagrams. Learn about the perturbative study of weak wave turbulence, exemplified by wind-driven ocean surface waves, and discover how stochastic classical field theories parallel quantum field theories. Understand the groundbreaking findings on the renormalization of quartic interactions, which challenge established assumptions in the field. Examine how the true dimensionless four-wave coupling differs parametrically from conventional estimates, and how the effective interaction either decays or experiences explosive growth depending on the coupling sign. Consider the implications of explosive growth for multi-wave bound states, drawing parallels to QCD confinement. Based on collaborative research presented by Vladimir Rosenhaus from CUNY, this seminar synthesizes findings from works with Michael Smolkin and Gregory Falkovich.
