Ultrafast Band Engineering and Transient Spin Currents in Antiferromagnetic Oxides

We report a dynamic structure and band engineering strategy with experimental protocols to induce indirect-to-direct band gap transitions and coherently oscillating pure spin-currents in three-dimensional antiferromagnets (AFM) using selective phononic excitations. In the Mott insulator LaTiO(3), we...
