In this work the end-to-end distance of an extensible discrete wormlike chain polymer as a function of the applied force has been calculated both numerically and analytically, the latter as an effective approximation. The numerical evaluation uses the transfer matrix formalism to obtain an exact calculation of the partition function, while the analytic derivations generalize the simple phenomenological formulas largely used up to now. The obtained formulas are simple enough to be implemented in the fit analysis of experimental data of semiflexible extensible polymers, with the result that the elastic parameters obtained are compatible with previous measurements, and more, their accuracy strongly improves in a large range of chain extensibility. info:eu-repo/grantAgreement/ES/DGA-FEDER/E36-20R info:eu-repo/grantAgreement/ES/MICINN/PID2020-113582GB-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.2 2023 PHYSICS, MATHEMATICAL 12 / 60 = 0.2 2023 Q1 T1 PHYSICS, FLUIDS & PLASMAS 17 / 40 = 0.425 2023 Q2 T2 0.805 2023 Condensed Matter Physics 2023 Q1 Statistics and Probability 2023 Q2 Statistical and Nonlinear Physics 2023 Q2 4.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Falo, Fernando Universidad de Zaragoza (orcid)0000-0002-9551-624X 2003 395 Universidad de Zaragoza Dpto.
