Description
It is well known that clouds of ultralight particles surrounding black holes produced by the superradiant instability can experience Landau-Zehner transitions if the black hole is part of a binary system.
We study the effect of orbital eccentricity, backreaction of the cloud onto it and observational possibilities with future gravitational-wave detectors like the Laser Interferometer Space Antenna, as well as the planned deciHertz gravitational-wave observatories. For black hole binaries with chirp masses below $10\,M_\odot$ , such effects would provide strong evidence for the existence of a new particle of mass between $10^{-13}$ to $10^{-11}\,\mathrm{eV}$.
