Plasmonic Coupling Dynamics of Silver Nanoparticles in an Optical Trap.

We investigate binding and plasmonic coupling between optically trapped 80 nm silver spheres using a combination of spectroscopic sensing and 3D interferometric laser particle tracking on a 1 μs time scale. We demonstrate that nanoparticle coupling can be either spontaneous or induced by another particle through confinement of diffusion. We reveal ultrafast entries and exits of nanoparticles in...

Stochastic dynamics of the magneto-optical trap

The cloud of cold atoms obtained from a magneto-optical trap is known to exhibit two types of instabilities in the regime of high atomic densities: stochastic instabilities and deterministic instabilities. In the present paper, the experimentally observed stochastic dynamics is described extensively. It is shown that it exists a variety of dynamical behaviors, which differ by the frequency comp...

Microbead dynamics in optical trap assisted nanopatterning

Optical near-field techniques allow one to overcome diffraction by positioning an optical element in close proximity to the surface of interest. In optical trap assisted nanopatterning, this optical element is a microbead optically trapped above the substrate in a liquid environment. Using high-speed microscopy, we show that under certain conditions, the laser pulse creates a gas bubble under t...

Rotational bosonic current in a quasi-condensate confined in an optical toroidal trap

We investigate the possibility of inducing a bosonic current which is rotational ( −→ ∇×−→v 6= −→ 0 ) in a pseudo 1D quasi-condensate confined in an optical toroidal trap. The stability of such a current is also analyzed using hydrodynamics approach. We find that such a current is uniform when the circular symmetry is preserved and energetically stable when the modes of elementary excitations a...

An Atom Trap Relying on Optical Pumping . ∗

We have investigated a new radiation pressure trap which relies on optical pumping and does not require any magnetic field. It employs six circularly polarized divergent beams and works on the red of a Jg −→ Je = Jg + 1 atomic transition with Jg ≥ 1/2. We have demonstrated this trap with cesium atoms from a vapour cell using the 852 nm Jg = 4 −→ Je = 5 resonance transition. The trap contained u...
