Creating and manipulating giant oscillating electric dipoles

In this talk I propose different schemes that employ ultrafast (attosecond) pulses and static or low frequency fields in order to create and manipulate giant oscillating electric dipoles. The numerical results are obtained by solving the time-dependent Schrödinger equation in reduced dimensionality models with soft-core Coulomb potentials for the H2+ molecule. I show that to create and maintain the dipoles in addition to breaking the molecular symmetry it is necessary to force a correlated electronic and nuclear motion, thus pushing the period of oscillation of the dipoles from the natural electronic (attosecond) timescale to the nuclear (femtosecond) timescale.
