Zusammenfassung
The exchange interaction determines the ordering of microscopic spins in magnetic materials. While often considered static, here we report calculations of time-dependent nonequilibrium exchange interactions in a Mott insulator. The results suggest that free charge carriers created by (photo) excitation can cause an ultrafast quench of the exchange interaction.
