Coherent orbital waves in the photo-induced insulator|[ndash]|metal dynamics of|[nbsp]|a magnetoresistive manganite

Abstract
Photo-excitation can drive strongly correlated electron insulators into competing conducting phases, resulting in giant and ultrafast changes of their electronic and magnetic properties. The underlying non-equilibrium dynamics involve many degrees of freedom at once, whereby sufficiently short optical pulses can trigger the corresponding collective modes of the solid along temporally coherent pathways.
