--- res: bibo_abstract: - In their Letter, Schreck, Bertrand, O'Hern and Shattuck [Phys. Rev. Lett. 107, 078301 (2011)] study nonlinearities in jammed particulate systems that arise when contacts are altered. They conclude that there is "no harmonic regime in the large system limit for all compressions" and "at jamming onset for any system size." Their argument rests on the claim that for finite-range repulsive potentials, of the form used in studies of jamming, the breaking or forming of a single contact is sufficient to destroy the linear regime. We dispute these conclusions and argue that linear response is both justified and essential for understanding the nature of the jammed solid. @eng bibo_authorlist: - foaf_Person: foaf_givenName: Carl Peter foaf_name: Goodrich, Carl Peter foaf_surname: Goodrich foaf_workInfoHomepage: http://www.librecat.org/personId=EB352CD2-F68A-11E9-89C5-A432E6697425 orcid: 0000-0002-1307-5074 - foaf_Person: foaf_givenName: Andrea J. foaf_name: Liu, Andrea J. foaf_surname: Liu - foaf_Person: foaf_givenName: Sidney R. foaf_name: Nagel, Sidney R. foaf_surname: Nagel bibo_doi: 10.1103/physrevlett.112.049801 bibo_issue: '4' bibo_volume: 112 dct_date: 2014^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0031-9007 - http://id.crossref.org/issn/1079-7114 dct_language: eng dct_publisher: American Physical Society@ dct_title: Comment on “Repulsive contact interactions make jammed particulate systems inherently nonharmonic”@ ...
