Inequivalence of fixed-force and fixed-extension statistical ensembles for a flexible polymer tethered to a planar substrate
S Dutta, P Benetatos - Soft Matter, 2018 - pubs.rsc.org
Recent advances in single macromolecule experiments have sparked interest in the
ensemble dependence of force–extension relations. The thermodynamic limit may not be …
