ITMP Seminar "Zero charge and confinement in turbulence"

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Sep 20, 18:00 (Moscow time). It will be organised via Zoom.

Speaker: Prof. Gregory Falkovich, Weizmann Institute of Science

Abstract: I will describe an attempt to do renormalization in turbulence, considering waves that interact weakly via four-wave scattering (such as sea waves, plasma waves, spin waves, and many others). By summing the series of the most UV-divergent terms in the perturbation theory, we show that the true dimensionless coupling is different from the naive estimate, and find that the effective interaction either decays or grows explosively with the cascade extent, depending on the sign of the new coupling. The explosive growth possibly signals the appearance of a multi-wave bound state (solitons, shocks, cusps) similar to confinement in quantum chromodynamics.

If you want to join the seminar please register here before 16:00, September 20 here.
