      abstract     = {We propose a new mechanism to produce a meron-antimeron
                      pair in a two dimensional antiferromagnet with an ultrafast
                      laser pulse via thermal Schwinger mechanism. Unlike
                      ultrafast skyrmion nucleation, this process conserves total
                      topological charge. We systematically show different stages
                      of the dynamics and define proper topological invariants to
                      characterise the configurations. The emergent structure can
                      retain its topological structure for up to 100ps. By
                      introducing a topological structure factor we show that pair
                      formation is robust against any random choice of initial
                      magnetic configuration and can survive against disorder. Our
                      findings demonstrate that the rich world of spin textures,
                      which goes beyond conventional skyrmions, can be reached
                      optically.},
