  text: Quantum control of the many-body wavefunction is a central challenge in quantum
    materials research, as it could yield a precise control knob to manipulate emergent
    phenomena. Floquet engineering, the coherent dressing of quantum states with periodic
    non-resonant optical fields, has become an important strategy for quantum control.
    Most applications to solid-state systems have targeted weakly interacting or single-ion
    states, leaving the manipulation of many-body wavefunctions largely unexplored.
    Here we use Floquet engineering to achieve quantum control of a strongly correlated
    Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant
    mid-infrared optical field coherently dresses the exciton wavefunction, driving
    its rotation between bright and dark states. We use resonant third-harmonic generation
    to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton
    states. Our work advances the quest towards programmable control of correlated
    states and exciton-based quantum sensing.

  text: "Magnetic interactions are thought to play a key role in the properties of
    many unconventional superconductors, including cuprates, iron pnictides, and square-planar
    nickelates. Superconductivity was also recently observed in the bilayer and trilayer
    Ruddlesden-Popper nickelates, the electronic structure of which is expected to
    differ from that of cuprates and square-planar nickelates. Here we study how electronic
    structure and magnetic interactions evolve with the number of layers, \U0001D45B,
    in thin film Ruddlesden-Popper nickelates Nd\U0001D45B+1⁢Ni\U0001D45B⁢O3⁢\U0001D45B+1
    with \U0001D45B=1,3, and 5 using resonant inelastic x-ray scattering (RIXS). The
    RIXS spectra are consistent with a high-spin |3⁢\U0001D4518⁢ \U0001D43F̲⟩ electronic
    configuration, resembling that of La2−\U0001D465⁢Sr\U0001D465⁢NiO4 and the parent
    perovskite, NdNiO3. The magnetic excitations soften to lower energy in the structurally
    self-doped, higher-\U0001D45B films. Our observations confirm that structural
    tuning is an effective route for altering electronic properties, such as magnetic
    superexchange, in this prominent family of materials."
