Query: Multi-polariton control in attosecond transient absorption of
  autoionizing states   Tunable attosecond transient absorption spectroscopy is an ideal tool for
studying and manipulating autoionization dynamics in the continuum. We
investigate near-resonant two-photon couplings between the bright 3s^-1 4p and
dark 3s^-1 4f autoionizing states of argon that lead to Autler-Townes like
interactions, forming entangled light-matter states, or polaritons. We observe
that one-photon couplings with intermediate dark states play an important role
in this interaction, leading to the formation of multiple polaritonic branches
whose energies exhibit avoided crossings as a function of the dressing-laser
frequency. Our experimental measurements and theoretical essential-state
simulations show good agreement and reveal how the delay, frequency, and
intensity of the dressing pulse govern the properties of autoionizing polariton
multiplets. These results demonstrate new pathways for quantum control of
autoionizing states with optical fields.
