Phys. Rev. Lett. 81, 1011–1014 (1998)Effect of Non-Pairwise-Additive Interactions on Bundles of Rodlike PolyelectrolytesReceived 14 January 1998; published in the issue dated 3 August 1998 Like-charged rigid polyelectrolytes can attract each other due to counterion-mediated interactions to form bundles. However, the resulting effective interactions between rods are not pairwise additive. Here we calculate the free energy of an N-rod bundle explicitly. We find that the breakdown of pairwise additivity dramatically affects the stability of bundles of N rods and leads to a barrier in the free energy that grows with increasing salt concentration. © 1998 The American Physical Society URL:
