Query: Effect of Disorder in a Three-Dimensional Layered Chern Insulator   We studied effects of disorder in a three dimensional layered Chern
insulator. By calculating the localization length and density of states
numerically, we found two distict types of metallic phases between Anderson
insulator and Chern insulator; one is diffusive metallic (DM) phase and the
other is renormalized Weyl semimetal (WSM) phase. We show that longitudinal
conductivity at the zero energy state remains finite in the renormalizd WSM
phase as well as in the DM phase, while goes to zero at a semimetal-metal
quantum phase transition point between these two. Based on the Einstein
relation combined with the self-consistent Born analysis, we give a
conductivity scaling near the quantum transition point.
