      abstract     = {We explore the impact of optical excitation using two
                      interfering ultrashort optical pulses on ultrafast
                      magnetization dynamics. Our investigation focuses on
                      Pt/Co/Pt multilayers and TbCo alloy samples, employing a
                      dual pump approach. We observe significant variations in the
                      dynamics of magnetization suppression and subsequent
                      recovery when triggered with two optical pulses of the same
                      polarization—essentially meeting conditions for
                      interference. Conversely, dynamics triggered with
                      cross-polarized pump beams exhibit expected similarity to
                      that triggered with a single pulse. Delving into the
                      underlying physical processes contributing to laser-induced
                      demagnetization and recovery dynamics, we find that our
                      current understanding cannot elucidate the observed trends.
                      Consequently, we propose that optical excitation with
                      interfering light possesses the capacity to induce
                      long-lasting alterations in the dynamics of angular
                      momentum.},
