In this Letter, we apply these approaches to run-and-tumble particles, which are designed to mimic the chemotactic behavior of bacteria and therefore exhibit complex dynamics due to their self-propulsion and random reorientation, making them difficult to control. Following a recent successful application to active Brownian particles, we find a general solution for the rapid control of 1D run-and-tumble particles in a harmonic potential. We demonstrate the effectiveness of our approach using numerical simulations and show that it can lead to a significant speedup compared to simple quenched protocols. Our results extend shortcut engineering to a wider class of active systems and demonstrate that it is a promising tool for controlling the dynamics of active matter, which has implications for a wide range of applications in fields such as materials science and biophysics.", "revisions": [ { "version": "v1", "updated": "2023-04-12T17:58:14.000Z" } ], "analyses": { "keywords": [ "run-and-tumble particles", "active matter", "results extend shortcut", "general solution", "specially designed external controls" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
