Erratum: Migration of an active colloidal cell in inhomogeneous environments (Journal of Chemical Physics (2022) 156 (134903) DOI: 10.1063/5.0084490)

We became aware that a relevant Ref. 1 (namely, Ref. 63 in the article2) was omitted from the result part “ACC filled with linear active Brownian particles” of the article (specifically, in the last paragraph of the right column on p. 7), although it was cited in another place (in the first paragraph of the right column on p. 5). In that Ref. 1, the chemotaxis of cargo-carrying active particles in a self-propelled force gradient was studied. In its conclusion part, the authors suggested that active bodies inside a container moving in a gradient of activity can give rise to chemotactic motion of the container, which is similar to a special case among our many systems, i.e., the ACC filled with linear active Brownian particles in the inhomogeneous self-propelled force environment. Clearly, our simulation result of the special case [Fig. 6(a)] is consistent with their suggestion. We thank the authors of Ref. 1 for helpful remarks.
