Control of arrival time using structured wave packets

نویسندگان

چکیده

Scattering dynamics are examined for Gaussian and non-Gaussian wave packets with identical momentum densities. Average arrival time delays, dwell times, phase delays calculated scattering from a square barrier, it is shown that the exhibit different average than packets. These differences result non-linear terms in function of packets, which alters self-interaction times Control delay can be achieved through adjustment phase, independent packet energy density.

Flexible tree-structured signal expansions using time-varying wavelet packets

In this paper, we address the problem of finding the best time-varying filter bank tree-structured representation for a signal. The tree is allowed to vary at regular intervals, and the spacing of these changes can be arbitrarily short. The question of how to choose tree-structured representations of signals based on filter banks has attracted considerable attention. Wavelets and their adaptive...

Airy wave packets accelerating in space-time

Although diffractive spreading is an unavoidable feature of all wave phenomena, certain waveforms can attain propagation-invariance. A lesser-explored strategy for achieving optical selfsimilar propagation exploits the modification of the spatio-temporal field structure when observed in reference frames moving at relativistic speeds. For such an observer, it is predicted that the associated Lor...

Geometric Segmentation Using Gaussian Wave Packets

We segment seismic data based on the geometric information provided by sparse gaussian wave packet representations. We use this information to for estimates an abundance of candidate curves for the identification of the wave fronts. A graph cut methodology is then employed to reduce the number of curves such that the data is well described by only few wave fronts.

Multi-Boson Correlations Using Wave-Packets

Brooding over bosons, wave packets and Bose Einstein correlations, we present a generic quantum mechanical system that contains arbitrary number of bosons characterized by wavepackets and that can undergo a Bose-Einstein condensation either by cooling, or increasing the number density of bosons, or by increasing the overlap of the multi-boson wave-packet states, achieved by changing the size of...

Time propagation of constrained coupled Gaussian wave packets.

The dynamics of quantum systems can be approximated by the time propagation of Gaussian wave packets. Applying a time dependent variational principle, the time evolution of the parameters of the coupled Gaussian wave packets can be calculated from a set of ordinary differential equations. Unfortunately, the set of equations is ill behaved in most practical applications, depending on the number ...
