for every particle i, with m i the particle mass, γ friction constant, x i the positions and v i the velocities. The conservative force f i results from the interparticle interaction, and the stochastic force w fulfills ⟨w⟩ = 0 and ⟨w i (t) w j (t ′ )⟩ = δ i j δ (tt ′ ). The mass of all particles is taken equal to the unity and the electrostatic interactions are calculated via the P3M method. For given topology, namely fixed N ch and N cross , various chain lengths N have been explored as well as different system parameters and microgel backbone charge. The simulation is initialized with a favorable microgel configuration of an equivalent neutral case, and we let the system evolve until reaching steady state (see Fig. ). Later, we measure the network radius of gyration and density distributions for characterizing the suspension and the microgel swelling.
