Project A2

Coherent control of correlated electron systems with ionizing light fields

Markus Drescher, Tim Laarmann

Laser-induced quantum correlations in molecular building blocks of graphene are characterized with pulse pairs covering the UV to soft X-ray spectrum. The settable phase delay reveals the electronic response with attosecond precision. This opens new vistas for dynamic control, because driven many-body states can be strongly coupled far from equilibrium. Together with projects B5, C1 and C7, light phase control will help unravelling the mystery of light-driven correlated quantum systems and provides protocols to steer charge rearrangements on the nanoscale in collaboration with projects A1-A7 and B8.
