Onsager theory of length-bidisperse hard rods: Evidence for a nematic-nematic critical point

TL;DR

This paper investigates the phase behavior of length-bidisperse hard rods using Onsager theory, providing evidence for a nematic-nematic critical point in such mixtures.

Contribution

It introduces a theoretical analysis of length-bidisperse hard rods and identifies a nematic-nematic critical point within their phase diagram.

Findings

Evidence for a nematic-nematic critical point

Phase diagram characteristics of bidisperse hard rods

Theoretical insights into rod mixture phase behavior

Abstract

This manuscript has been withdrawn because of significant overlap with an existing paper (Szabolcs Varga and Istvan Szalai, "Phase diagrams of binary mixtures of hard rods in an external orientational field", Phys. Chem. Chem. Phys., 2:1955-1959, 2000) of which we were, unfortunately, unaware when submitting our manuscript.
