The wave packet propagation using wavelets
It is demonstrated that the wavelets can be used to considerably speed up simulations of the wave packet propagation in multiscale systems. Extremely high efficiency is obtained in the representation of both bound and continuum states. The new method is compared with the fast Fourier algorithm. Depending on ratios of typical scales of a quantum system in question, the wavelet method appears to ...
متن کاملSiD2 using three-dimensional wave packet propagation
Dissociations after the à B1→ B̃ A1 photoexcitation of SiH2, SiHD, and SiD2 were studied to investigate excited-state dynamics and effects of the initial vibrational state. The cross section for the photodissociation relative to SiH2 B̃ →Si D +H2 and the rovibrational population of the H2 fragment were computed using the wave packet propagation technique based on the three-dimensional potential e...
متن کاملSeismic Wave-Field Propagation Modelling using the Euler Method
Wave-field extrapolation based on solving the wave equation is an important step in seismic modeling and needs a high level of accuracy. It has been implemented through a various numerical methods such as finite difference method as the most popular and conventional one. Moreover, the main drawbacks of the finite difference method are the low level of accuracy and the numerical dispersion for l...
متن کاملNeutrino wave packet propagation in gravitational fields
We discuss the propagation of neutrino wave packets in a Lense-Thirring spacetime using a gravitational phase approach. We show that the neutrino oscillation length is altered by gravitational corrections and that neutrinos are subject to helicity flip induced by stellar rotation. For the case of a rapidly rotating neutron star, we show that absolute neutrino masses can be derived, in principle...
متن کاملChemical Wave Packet Propagation, Reflection, and Spreading
scheme: Reactions 10-13 constitute the well-known Brusselator model.16 The additional steps 14 and 15 describe a reversible interconversion between the activator (X) and an unreactive form (Z). This interconversion may arise, for example, in the BZ-AOT system, from transfer of the activator from one phase (aqueous) to another (oil), where it is unreactive because of the absence of reaction part...
