Summary
Materials with strong coupling between electrons, spin and lattice have fascinating properties. One example is the abrupt transition from an electrically insulating material into an electrically conducting state at a critical temperature. Femtosecond laser pulses are used to trigger such transitions and to investigate their dynamics on ultrashort time scales. In this way, an extended microscopic understanding of materials with strongly correlated degrees of freedom is achieved. This knowledge may be helpful in the search for materials with new and optimized electronic properties.
