      abstract     = {Among antiferromagnetic materials, Mn2Au is one of the most
                      intensively studied, and it serves as a very popular
                      platform for testing various ideas related to
                      antiferromagnetic magnetotransport and dynamics. Since
                      recently, this material has also attracted considerable
                      interest in the context of optical properties and
                      optically-driven antiferromagnetic switching. In this work,
                      we use first principles methods to explore the physics of
                      charge photocurrents, spin photocurrents, and the inverse
                      Faraday effect in antiferromagnetic Mn2Au. We predict the
                      symmetry and magnitude of these effects and speculate that
                      they can be used for tracking the dynamics of staggered
                      moments during switching. Our calculations reveal the
                      emergence of large photocurrents of spin in collinear Mn2Au,
                      whose properties can be understood as a result of a
                      non-linear optical version of the spin Hall effect, which we
                      refer to as the photospin Hall effect, encoded into the
                      relation between the driving charge and resulting spin
                      photocurrents. Moreover, we suggest that even a very small
                      canting in Mn2Au can give rise to colossal spin
                      photocurrents that are chiral in flavor. We conclude that
                      the combination of staggered magnetization with the
                      structural and electronic properties of this material
                      results in a unique blend of prominent photocurrents, which
                      makes Mn2Au a unique platform for advanced optospintronics
                      applications.},
