      abstract     = {Photoexcited states of tungsten trioxide (WO$_3$) were
                      observed using femtosecond high-energy-resolution
                      fluorescence detection X-ray Absorption Spectra (HERFD-XAS)
                      and resonant X-ray emission spectra (RXES). In the initial
                      state of the photoexcitation (∼100 fs), the W L$_3$ edge
                      XAS shifts to lower energy and the energy levels of the
                      t$_{2g}$ and e$_g$ peaks are modulated due to the
                      photoexcited electrons in the conduction band. The
                      electronic state of the photoexcited W atoms is modified by
                      500 fs. The crystal field splitting between the t$_{2g}$ and
                      e$_g$ peaks shrinks by 500 fs, which indicates local
                      structural changes around the W atoms due to the formation
                      of polarons. HERFD-XAS and RXES provide more details about
                      the early state of the photoexcited states of WO$_3$. This
                      work demonstrates that the detailed dynamics of 5d elements
                      in the femtosecond range can be addressed with
                      HERFD-XAS/RXES.},
