  In this letter, we present the first numerical study on the structural and
dynamical properties of a quasi-two-dimensional (q2D) binary complex plasma
with Langevin dynamics simulation. The effect of interaction with
non-reciprocity on the structure is investigated by comparing systems with pure
Yukawa and with point-wake Yukawa interactions. The long-time alpha-relaxation
for the latter system is revealed by plotting and analyzing the intermediate
scattering function. The results clearly indicate that a q2D binary complex
plasma is a suitable model system to study the dynamics of a glass former. The
non-reciprocity of the interactions shifts the glass formation significantly
but leads to the same qualitative signatures as in the reciprocal case.
