      abstract     = {Tuning and stabilizing topological states, such as Weyl
                      semimetals, Dirac semimetals or topological insulators, is
                      emerging as one of the major topics in materials science.
                      Periodic driving of many-body systems offers a platform to
                      design Floquet states of matter with tunable electronic
                      properties on ultrafast timescales. Here we show by first
                      principles calculations how femtosecond laser pulses with
                      circularly polarized light can be used to switch between
                      Weyl semimetal, Dirac semimetal and topological insulator
                      states in a prototypical three-dimensional (3D) Dirac
                      material, Na3Bi. Our findings are general and apply to any
                      3D Dirac semimetal. We discuss the concept of time-dependent
                      bands and steering of Floquet–Weyl points and demonstrate
                      how light can enhance topological protection against lattice
                      perturbations. This work has potential practical
                      implications for the ultrafast switching of materials
                      properties, such as optical band gaps or anomalous
                      magnetoresistance.},
