Query: Microwave susceptibility observation of interacting many-body Andreev
  states   Electrostatic charging affects the many-body spectrum of Andreev states, yet
its influence on their microwave properties has not been elucidated. We
developed a circuit quantum electrodynamics probe that, in addition to
transition spectroscopy, measures the microwave susceptibility of different
states of a semiconductor nanowire weak link with a single dominant
(spin-degenerate) Andreev level. We found that the microwave susceptibility
does not exhibit a particle-hole symmetry, which we qualitatively explain as an
influence of Coulomb interaction. Moreover, our state-selective measurement
reveals a large, $\pi$-phase shifted contribution to the response common to all
many-body states which can be interpreted as arising from a phase-dependent
continuum in the superconducting density of states.
