    abstract={Intense x-ray free-electron laser pulses can induce multiple sequences of inner-shell ionization events and
    accompanying decay processes in atoms, producing highly-charged atomic ions. In general, x-ray
    multiphoton ionization dynamics have been described in terms of time-dependent populations of the
    electronic configurations visited during the ionization dynamics, neglecting individual state-to-state
    transition rates and energies. Combining a state-resolved electronic-structure method based on first-order
    many-body perturbation theory [1] with a Monte Carlo rate-equation method [2] enables us to study state-
    resolved dynamics based on time-dependent quantum-state populations. Here we present a theoretical
    study of state-resolved x-ray multiphoton ionization dynamics of neon atoms [3]. Our results demonstrate
    that configuration-based and state-resolved calculations provide similar charge-state distributions, but
    differences are visible when resonant excitations are involved. Calculated time-resolved spectra of ions,
    electrons, and photons allow us to investigate ultrafast dynamics of x-ray multiphoton ionization in detail.
    In addition, we will present a comparison with a recent experiment on Ne [4] and discuss how to handle
    the extremely large number of atomic parameters involved in state-resolved dynamics calculations via
    machine-learning techniques [5].
