Emergence of exponentially accurate reflected or tunneling semiclassical wave packets Joye, Alain


We review the one dimensional time–dependent scattering of a quantum mechanical wave packet at a potential barrier for energies larger, respectively lower, than the barrier height, in the semi–classical regime. Making use of complex WKB methods, we provide a precise space–time description of the reflected, respectively transmitted, exponentially small wave packets. This talk is based on two joint works with V. Betz and S. Teufel and with V. Gradinaru and G. Hagedorn.
