Candidate-dependent extremal alignment in topological active matter generates self-confined, spatially structured flocks by factorizing decision utility into average score times neighbor count.
Number fluctuation signals N(t) distinguish self-propelled particle models via differences in reorientation dynamics.
Wedge confinement changes the magnitude and direction of a self-diffusiophoretic particle's velocity through reflected concentration fields in the far-field limit.
An inertial chiral active Brownian particle confined in a harmonic potential transitions from Gaussian to platykurtic position distribution when harmonic and chiral frequencies match, confirmed by kurtosis dip and non-monotonic MSD.
