Quantum scattering in one-dimensional periodic structures: A Green's function approach solved through continued fractions

LRN Oliveira, MGE da Luz - Physical Review B, 2024 - APS
In the present contribution, we discuss quantum scattering in 1D periodic finite lattices of N
localized potentials by means of an exact Green's function approach. By considering …
