The reasonable and unreasonable effectiveness of hydrodynamics in exotic quantum matter

Hydrodynamics has a long and glorious history, describing phenomena ranging from flows of water, patterns of weather, to star and galaxy formations. During the last decade, it has also played important and often surprising roles in characterizing various types of exotic quantum matter. In particular, it helped formulating a new class of quantum matter: quantum liquids without quasiparticles. I will briefly review these stories and explain physical reasons behind these phenomenal new successes of hydrodynamics. I will then discuss some recent theoretical developments in reformulating hydrodynamics based on action principle. The reformulation enables a new recent application: characterizing quantum many-body chaos, where the role of hydrodynamics has been rather unexpected and its success remains mysterious.


The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium. [Registration may close earlier, when 80 persons have signed up]
