An Analytic Approach to the Wave Packet Formalism in Oscillation Phenomena
Alex E. Bernardini, Stefano De Leo
We introduce an approximation scheme to perform an analytic study of the oscillation phenomena in a pedagogical and comprehensive way. By using Gaussian wave packets, we show that…
Tunnelling Through Two Barriers
Stefano De Leo, Pietro Rotelli
Recent studies of the tunnelling through two opaque barriers claim that the transit time is independent of the barrier widths and of the separation distance between the barriers. W…
Above potential barrier diffusion
A. E. Bernardini, S. De Leo, P. Rotelli
The stationary phase method is applied to diffusion by a potential barrier for an incoming wave packet with energies greater then the barrier height. It is observed that a direct a…
Survival law in a potential model
S. De Leo, P. Rotelli
The radial equation of a simple potential model has long been known to yield an exponential decay law in lowest order (Breit-Wigner) approximation. We demonstrate that if the calcu…
Amplification of coupling for Yukawa potentials
S. De Leo, P. Rotelli
It is well known that Yukawa potentials permit bound states in the Schrodinger equation only if the ratio of the exchanged mass to bound mass is below a critical multiple of the co…
