Bogoliubov-Cerenkov radiation in a Bose-Einstein condensate flowing against an obstacle
, 2006 We study the density modulation that appears in a Bose-Einstein condensate flowing with supersonic velocity against an obstacle. The experimental density profiles observed at JILA are reproduced by a numerical integration of the Gross-Pitaevskii equation

Serfati solutions to the 2D Euler equations on exterior domains [PDF]
, 2014 We prove existence and uniqueness of a weak solution to the incompressible 2D Euler equations in the exterior of a bounded smooth obstacle when the initial data is a bounded divergence-free velocity field having bounded scalar curl.
