Title: | Comment on “Generalized exclusion processes: Transport coefficients” | Authors: | BECKER, Thijs NELISSEN, Kwinten CLEUREN, Bart Partoens, Bart VAN DEN BROECK, Christian |
Issue Date: | 2016 | Source: | PHYSICAL REVIEW E, 93 (4) | Abstract: | In a recent paper, Arita et al. [Phys. Rev. E 90, 052108 (2014)] consider the transport properties of a class of generalized exclusion processes. Analytical expressions for the transport-diffusion coefficient are derived by ignoring correlations. It is claimed that these expressions become exact in the hydrodynamic limit. In this Comment, we point out that (i) the influence of correlations upon the diffusion does not vanish in the hydrodynamic limit, and (ii) the expressions for the self- and transport diffusion derived by Arita et al. are special cases of results derived in Becker et al. [Phys. Rev. Lett. 111, 110601 (2013)]. | Notes: | Becker, T (reprint author), Hasselt Univ, B-3590 Diepenbeek, Belgium. thijsbecker@gmail.com | Document URI: | http://hdl.handle.net/1942/21417 | ISSN: | 2470-0045 | e-ISSN: | 2470-0053 | DOI: | 10.1103/PhysRevE.93.046101 | ISI #: | 000374962100019 | Rights: | © 2016 American Physical Society | Category: | A2 | Type: | Journal Contribution |
