The possibility to control charge migration in molecules using femtosecond laser pulses is studied, which may have applications in the laser control of fundamental chemical processes. A method is introduced to realize dispersion-free transport of a localized wave packet on a lattice by devising a Hamiltonian so that the wave packet perfectly splits and interferes with itself, providing a new avenue in the field of perfect state transfer.
A possible setup for a quantum-repeater network using satellite links is demonstrated, and it is shown that this approach allows entanglement creation at viable rates over global distances that are inaccessible via direct transmission through optical fibers. In situ fluorescence detection of atoms in a dipole trap using a blue-detuned probe beam in addition to the standard cooling laser beams is demonstrated, and it is shown that atom numbers up to about can be detected with sub-Poissonian precision.
Intensity- and phase-noise correlations in a dual-frequency VECSEL are studied theoretically and experimentally, and it is shown how the results can be interpreted in terms of the linear response of two coupled overdamped oscillators. A proposal is presented for the optomechanical levitation of objects with enhanced isolation from the environment, which is of practical interest for a variety of applications ranging from frequency-tuned high-resolution force sensing to quantum optomechanics experiments.
