We analyzed the dynamic evolution of an ensemble of electrons performing macroscopic resonant tunneling for room-temperature millimeter-sized Coulomb oscillation in Ni-Nb-Zr-H glassy alloys as a function of the cluster size and boundary length using a one-dimensional Kronig-Penny model with a stepwise potential. The reflection coefficient showed a stagnant chaos around a narrow torus for a superlattice with a cluster size of 0.55 nm and a boundary distance of 0.
