Wegner estimate for Landau-breather Hamiltonians
  We consider Landau Hamiltonians with a weak coupling random electric potential of breather type.   Under appropriate assumptions we prove a Wegner estimate.   It implies the Hoelder continuity of the integrated density of states.   The main challenge is the problem how to deal with non-linear dependence on the random parameters.
