A one-dimensional model for theoretical analysis of single molecule experiments

TL;DR

This paper compares two polymer stretching experiments using a one-dimensional model, revealing that their force-extension relations generally differ but converge under specific conditions.

Contribution

It introduces a one-dimensional model to analyze and compare force-extension relations in different single molecule experiments, highlighting conditions for their equivalence.

Findings

Force-extension relations generally differ between experiments.

Under certain limits, the relations coincide.

The model clarifies conditions for equivalence.

Abstract

In this paper we compare two polymer stretching experiments. The outcome of both experiments is a force-extension relation. We use a one-dimensional model to show that in general the two quantities are not equal. In certain limits, however, both force-extension relations coincide.
