WAVE Packet Transmission Method for Railroad WAVE Communication

wave packet

The zero point field and the reduction of the wave packet in semiclassical electrodynamics. Abstract In the classical theory, an electromagnetic field obeying Maxwell's equations cannot be absorbed quickly by matter, so that it remains a zero point field. Splitting the total, genuine electromagnetic field into the sum of a conventional field and a zero point field is physically meaningless unti...

Electronic Transmission Wave Function of Disordered Graphene by Direct Method and Green's Function Method

We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...

An adaptive pseudospectral method for wave packet dynamics.

We solve the time-dependent Schrödinger equation for molecular dynamics using a pseudospectral method with global, exponentially decaying, Hagedorn basis functions. The approximation properties of the Hagedorn basis depend strongly on the scaling of the spatial coordinates. Using results from control theory we develop a time-dependent scaling which adaptively matches the basis to the wave packe...

Gaussian wave-packet method for systems with Coulomb interactions

Gaussian wave packets (GWPs) are well suited as basis functions to describe the time evolution of arbitrary wave functions in systems with nonsingular smooth potentials. They are less so in atomic systems on account of the singular behavior of the Coulomb potential. We present a timedependent variational method that makes the use of GWPs possible in the description of propagation of quantum sta...
