Wave packet tunneling

Wave packet tunneling

The tunneling of Gaussian wave packets has been investigated by numerically solving the one-dimensional Schrödinger equation. The shape of wave packets interacting with a square barrier has been monitored for various values of the barrier width, height and initial width of the wave packet. Compared to the case of free propagation, the maximum of a tunneled wave packet exhibits a shift, which ca...

Simulation of wave packet tunneling of interacting identical particles.

We demonstrate a different method of simulation of nonstationary quantum processes, considering the tunneling of two interacting identical particles, represented by wave packets. The used method of quantum molecular dynamics (WMD) is based on the Wigner representation of quantum mechanics. In the context of this method ensembles of classical trajectories are used to solve quantum Wigner-Liouvil...

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...

Low energy wave packet tunneling from a parabolic potential well through a high potential barrier

The problem of wave packet tunneling in a potential V (x) = (mω2/2) ( x2 − δxν ) with ν > 2 is considered in the case when the barrier height is much greater than h̄ω and the difference between the average energy of the packet and the oscillator ground state energy h̄ω/2 is sufficiently small. The universal Poisson distribution of the partial tunneling rates from the oscillator energy levels is d...
