Decoherence due to elastic Rayleigh scattering.

Superradiant light scattering from a moving Bose–Einstein condensate

We investigate the interaction of a moving BEC with a far detuned laser beam. Superradiant Rayleigh scattering arises from the spontaneous formation of a matter-wave grating due to the interference of two wavepackets with different momenta. The system is described by the CARL-BEC model which is a generalization of the Gross–Pitaevskii model to include the self-consistent evolution of the scatte...

Decoherence of quantum kinematical correlations: Elastic scattering of identical particles

Surface scattering analysis of phonon transport in the quantum limit using an elastic model

We have investigated the effect on phonon energy transport in mesoscopic systems and the reduction in the thermal conductance in the quantum limit due to phonon scattering by surface roughness, using full threedimensional elasticity theory for an elastic beam with a rectangular cross section. At low frequencies, we find power laws for the scattering coefficients that are strongly mode dependent...

Damped oscillations in the energy autocorrelation functions of the 58 Ni + 46 Ti elastic and 58 Ni + 62 Ni elastic and inelastic scattering cross sections

Structures of non-statistical character, recently observed in 58Ni +46 Ti elastic and 58Ni +62 Ni elastic and inelastic excitation functions, produce damped oscillations in the cross section energy autocorrelation functions. The analysis of these damped oscillations in terms of S-matrix spin and parity decoherence indicates, as a possible interpretation, damping of the coherent rotational motio...

Rayleigh Scattering Spectroscopy

Single-wall carbon nanotubes can be probed optically by elastic light scattering. This effect forms the basis of a technique, termed Rayleigh scattering spectroscopy, for the study of individual nanotubes. Spectroscopic information on the electronic transitions of both semiconducting and metallic nanotubes is obtained by measuring the elastic scattering cross section as a function of photon ene...
