Quantum transmission in 1D disordered stealthy hyperuniform Kronig--Penney-like models

Disordered stealthy hyperuniform (SHU) systems are emerging as platforms for controlling classical and quantum transport due to vanishing single-scattering contributions in the stealthy regime. Here, to our knowledge, we present the first perturbation theory of one-dimensional quantum transport through a continuum of identical point scatterers with SHU positional disorder. Our perturbation theory indicates the exact cancellation of all the lower-order terms due to the Fourier-space stealthy condition S(q)=0, and the further suppression of the lowest non-vanishing fourth order in the Lyapunov exponent λ(k) due to the real-space hyperuniform constraint limlimits_{Dtoinfty}σ_D^2=c<infty. Our findings presents universal implications of the general wave-propagation phenomena in disordered SHU systems.
