Random Coupling Models

Tuesday 27 Feb 2024, 15:30 → 17:30 US/Eastern

There is a long history, in both classical and quantum physics, of models with couplings that are random variables.  An example is the Sachdev-Ye-Kitaev model which, over the past decade, has emerged as the harmonic oscillator of chaotic many-body systems. We discuss the model and some of its applications within high energy theory and condensed matter physics. We conclude with a discussion of how quantum field theory techniques may be useful in understanding the statistics of random ocean waves and the observed power law spectrum.
