Polar flock with bond disorder

Understanding the collective behaviour of self-propelled particles (SPP’s) is an active area of
research. Although collection of SPP’s are made of similar particles. But each individual can differ
deu to their much details of biological complexity. We focus on difference in interaction ability
with neighbours. Hence in this study we introduced a collection of SPP’s interecting through a
short range Vicsek type alignment interaction, but strength of alignment is different for different
particle and obtained from random distribution. Equalibrium analog of one model is XY-model with
bond disorder. we find that presence of such bond disorder, long range ordering (L.R.O) remains
unchanged as for clean system. Also ordering kinetics remain uneffected but large disorder.
