Finite-energy weak solutions and relaxation for a compressible kinetic--fluid system with locally averaged Brinkman force
Young-Pil Choi, Roman Shvydkoy
We study a kinetic--fluid system in which a Vlasov or Vlasov--Fokker--Planck equation is coupled to the compressible Navier--Stokes equations with density-dependent viscosities thr…

Multiphoton ionization with three-dimensional light fields
Darius Köhnke, Hans-Christian Ahlswede, Tim Bayer +1
We report the first observation of free-electron angular momentum wave packets generated by atomic multiphoton ionization with bichromatic three-dimensional (3D) polarization-tailo…
