  We study the Kibble-Zurek mechanism in a 2d holographic p-wave superconductor
model with a homogeneous source quench on the critical point. We derive, on
general grounds, the scaling of the Kibble-Zurek time, which marks
breaking-down of adiabaticity. It is expressed in terms of four critical
exponents, including three static and one dynamical exponents. Via explicit
calculations within a holographic model, we confirm the scaling of the
Kibble-Zurek time and obtain the scaling functions in the quench process. We
find the results are formally similar to a homogeneous quench in a higher
dimensional holographic s-wave superconductor. The similarity is due to the
special type of quench we take. We expect differences in the quench dynamics if
the condition of homogeneous source and dominance of critical mode are relaxed.
