  In the framework of anti-de Sitter space/conformal field theory (AdS/CFT), we
study the pole-skipping phenomenon of the holographic correlators of boundary
operators. We explore the locations of the pole-skipping points case by case
with the models of $U(1)$-gauged form fields propagating in the asymptotic AdS
bulk of finite temperature. In general, in different cases all the first-order
points are located at the Matsubara frequency with corresponding wave vectors
regularly dispersed in the momentum space. Specifically, in the massless cases
with $U(1)$ symmetry, the wave vectors of the pole-skipping points have a
form-number dependence, and a trans-mode equivalence in the dual fields is
found in correspondence with electromagnetic duality. In the massive cases with
explicit symmetry breaking, we find that the appearance of a non-zero mass
yields extra pole-skipping points which reduce to the massless results in zero
mass limit. We expect in such kind of pole-skipping properties implications of
distinctive physics in the chaotic systems. Our near-horizon computation is
verified with the double-trace method especially in the example of 2-form where
there is dimension-dependent boundary divergence. We illustrate in these cases
that the pole-skipping properties of the holographic correlators are determined
by the IR physics, consistent with the ordinary cases in previous studies.
