Scattering of wave packets with phases

Core Scattering of Stark Wave Packets

Visualization of the core-scattering dynamics of Rydberg wave packets.

We present classical and quantum studies of the scattering dynamics of Rydberg electron wave packets from the electronic core of alkali atoms. In quantum systems an ideal state for studying such effects is an angularly localized wavepacket in which the primary effect of the scattering is to cause precession. The scattering is enhanced by the application of an external dc electric field. We calc...

Transfer and scattering of wave packets by a nonlinear trap.

In the framework of a one-dimensional model with a tightly localized self-attractive nonlinearity, we study the formation and transfer (dragging) of a trapped mode by "nonlinear tweezers," as well as the scattering of coherent linear wave packets on the stationary localized nonlinearity. The use of a nonlinear trap for dragging allows one to pick up and transfer the relevant structures without ...

Self-Interfering Wave Packets.

We study the propagation of noninteracting polariton wave packets. We show how two qualitatively different concepts of mass that arise from the peculiar polariton dispersion lead to a new type of particlelike object from noninteracting fields-much like self-accelerating beams-shaped by the Rabi coupling out of Gaussian initial states. A divergence and change of sign of the diffusive mass result...

Autoionizing Rydberg wave packets.

In this paper we present some of the general features of autoionizing Rydberg wave packets. We assume the wave packets are generated by a short, perturbative laser pulse that excites the electronic wave function to a coherent distribution of final state energies in the autoionizing regime. We describe a possible experiment for generating and detecting these autoionizing wave packets. A physical...
