Universal Ratios of Characteristic Lengths in Semidilute Polymer Solutions

Jung-Ren Huang, T. A. Witten

We use experimental and simulation data from the literature to infer five characteristic lengths, denoted ${\xi }_s$, ${\xi }_f$, ${\xi }_{\Pi }$, ${\xi }_{\varphi }$, and ${\xi }_D$ of a semidilute polymer solution. Th…
