Stationary bound states of massless scalar fields around black holes and black hole analogues

We discuss stationary bound states, a.k.a. clouds, for a massless test scalar field around Kerr black holes (BHs) and spinning acoustic BH analogues. In view of the absence of a mass term, the trapping is achieved via enclosing the BH - scalar field system in a cavity and imposing Dirichlet or Neuma...
