In this study, we investigate the behaviors and dynamics of self-propelled particles with active reorientation (AR) in a double-well potential. We explore the competition between AR and external potentials, revealing that self-propelled particles exhibit flocking and clustering behaviors in an asymmetric potential trap. Through molecular dynamics simulations, we obtain a phase diagram that illustrates flocking behavior as a function of active reorientation and potential asymmetry. We compare the responses of inactive and active particles to the potential, finding that active reorientation significantly increases aggregation on one side of the asymmetric potential well. Additionally, by calculating the mean squared displacement and scaling exponent, we identify distinct diffusion regimes. Our findings demonstrate that active particles with active reorientation are more sensitive to variations in double-well potentials.
