  bibo_abstract:
  - The coherent optical manipulation of solids is emerging as a promising way to
    engineer novel quantum states of matter. The strong time-periodic potential of
    intense laser light can be used to generate hybrid photon-electron states. Interaction
    of light with Bloch states leads to Floquet-Bloch states, which are essential
    in realizing new photo-induced quantum phases. Similarly, dressing of free-electron
    states near the surface of a solid generates Volkov states, which are used to
    study nonlinear optics in atoms and semiconductors. The interaction of these two
    dynamic states with each other remains an open experimental problem. Here we use
    time- and angle-resolved photoemission spectroscopy (Tr-ARPES) to selectively
    study the transition between these two states on the surface of the topological
    insulator Bi2Se3. We find that the coupling between the two strongly depends on
    the electron momentum, providing a route to enhance or inhibit it. Moreover, by
    controlling the light polarization we can negate Volkov states to generate pure
    Floquet-Bloch states. This work establishes a systematic path for the coherent
    manipulation of solids via light-matter interaction.@eng
