One response on “Colored Noise Models of Active Particles”

  1. Claudio says:

    I just wanted to add to the nice review of Cates and Nardini that, according to Hanggi and Jung, the multidimensional UCNA should become asymptotically exact also for an infinite correlation time.
    This happens in those points of phase space where all the eigenvalues of the Hessian matrix associated with the potential are positive.
    This may sound as a very restrictive condition, however it is met in some interesting cases. This is for example the case of 2 particles moving in 1d interacting via an inverse power-law potential (soft spheres). Moreover this is the case when particles are confined by a very steep repulsive potential that is spherically symmetric. Both cases are studied in paper I.

Members are invited to comment on the chosen papers and refer only to papers intimately related to the papers selected. Other comments and suggestions can be transmitted to the organizers through the 'Guest book' link. These comments will be put on the web-site and the archives so that they can be read by other members. Just as in the Guidelines to the Corresponding Members, we suggest that the comments be confined to substantive issues of science and in order to illuminate the subject matter. A collegial and respectful tone is suggested. Issues of priority should not be raised in the comments.
