Recurrence in resonant transmission of one-dimensional array of delta potentials

Quantum Physics 2014-02-05 v1

Abstract

The resonant transmission of a moving particle which interacts with an one-dimensional array of N delta-function potentials is investigated. A suitable transfer matrix formulation is used to obtain the particle transmission. We give the parameters for perfect tunnelling and the transcendental equation for the quasi-bound state energies for N = 2, 3 and 4. Conditions for perfect tunnelling and resonant transmission are discussed for arrays with arbitrary N. A model to explain how the tunnelling energy filter works in these systems is proposed here.
