The Leontovich boundary condition is a boundary condition in classical electrodynamics that relates to the tangential components of the electric Et and magnetic Ht fields on the surface of well-conducting bodies. (Wikipedia).
Vorticity and flow direction of Von Kármán vortices behind an airplane wing
Here is yet another simulation of a compressible Euler flow around a wing-shaped profile. The main difference with previous simulations such as https://youtu.be/XptnkvZF_Es is that there is no more force field from the wing. Indeed, using such a force field seemed to be a source of instabi

Leonid Polterovich: Quantum footprints of symplectic rigidity
Abstract: We discuss interactions between quantum mechanics and symplectic topology including a link between symplectic displacement energy, a fundamental notion of symplectic dynamics, and the quantum speed limit, a universal constraint on the speed of quantum-mechanical processes. Joint
