      abstract     = {CeRh$_2$As$_2$ is a new multiphase superconductor with
                      strong suggestions for an additional itinerant multipolar
                      ordered phase. The modeling of the low-temperature
                      properties of this heavy-fermion compound requires a quartet
                      Ce$^{3+}$ crystal-field ground state. Here, we provide the
                      evidence for the formation of such a quartet state using
                      x-ray spectroscopy. Core-level photoelectron and x-ray
                      absorption spectroscopy confirm the presence of Kondo
                      hybridization in CeRh$_2$As$_2$. The temperature dependence
                      of the linear dichroism unambiguously reveals the impact of
                      Kondo physics for coupling the Kramer’s doublets into an
                      effective quasiquartet. Nonresonant inelastic x-ray
                      scattering data find that the $|Γ^−_7⟩$ state with its
                      lobes along the 110 direction of the tetragonal structure
                      (xy orientation) contributes most to the multiorbital ground
                      state of CeRh$_2$As$_2$.},
