In this work we study a two-dimensional system composed by Active BrownianParticles (ABPs) interacting via a repulsive potential with two-length-scales,a soft shell and a hard-core. Depending on the ratio between the strength ofthe soft shell barrier and the activity, we find two regimes: If this ratio ismuch larger or smaller than 1, the observed behaviour is comparable with ABPsinteracting via a single length-scale potential. If this ratio is similar to 1,the two length-scales are relevant for both structure and dynamical properties.On the structural side, when the system exhibits a motility induced phaseseparation, the dense phase is characterised by new and more complex structurescompared with the hexatic phase observed in single length-scale systems. On thedynamical side, as far as we are aware, this is the first representation of ananomalous dynamics in active particles.
