Coherent transients in optical lattices

Optical pulse shaping using optical coherent transients.

Using multiple temporally-overlapped, frequency offset and phase-tuned, linear frequency chirps, a new method of multi-GHz optical coherent transient optical pulse shaping and processing in inhomogeneously broadened rare-earth doped crystals is proposed. Using this technique with properly chirped laser sources, multi-GHz processing can be controlled with conventional low-bandwidth electronics a...

Coherent cold collisions with neutral atoms in optical lattices.

By loading a Bose-Einstein condensate into a three-dimensional optical lattice potential, we have been able to demonstrate several fundamental aspects of coherent cold collisions between neutral atoms. We show experimentally how such collisions lead to a well-defined phase shift in the corresponding many-body wave function. The experimental realization of such interactions can be fundamental fo...

Coherent Directed Transport of Neutral Atoms in Unmodulated Optical Lattices

We introduce a fully coherent way for directed transport of neutral atoms in optical lattices by regularly performing phase shifts on the lattice potential during the free evolution of the system. This paves the way for realizing quantum gates and entanglement generation by bringing two individual atoms in the proximity of each other and let them interact. The speed of our protocol is truly det...

Accurate description of optical precursors and their relation to weak-field coherent optical transients

We study theoretically the propagation of a step-modulated optical field as it passes through a dispersive dielectric made up of a dilute collection of oscillators characterized by a single narrow-band resonance. The propagated field is given in terms of an integral of a Fourier type, which cannot be evaluated even for simple models of the dispersive dielectric. The fact that the oscillators ha...
