AB  - We study the quantum Goos-Hanchen (GH) effect for wave-packet dynamics at a normal/superconductor (NS) interface. We find that the effect is amplified by a factor (E-F/Delta), with E-F the Fermi energy and Delta the gap. Interestingly, the GH effect appears only as a time delay delta t without any lateral shift, and the corresponding delay length is about (E-F/Delta)lambda(F), with lambda(F) the Fermi wavelength. This makes the NS interface sticky when Delta LT LT E-F, since typically GH effects are of wavelength order. This sticky behavior can be further enhanced by a resonance mode in the NSNS interface. Finally, for a large Delta, the resonance-mode effect makes a transition from the Andreev to the specular reflection as the width of the sandwiched superconductor is reduced. Copyright (C) EPLA, 2013

AB  - It has recently been established that quantum statistics can play a crucial role in quantum escape. Here we demonstrate that boundary conditions can be equally important-moreover, in certain cases, may lead to a complete suppression of the escape. Our results are exact and hold for arbitrarily many particles. Copyright (c) EPLA, 2012
