2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/21201We discuss the phenomenon of spontaneous self-compactification in a model colloidal system, proposed in a recent work on DNA-mediated self-assembly. We focus on the effect of thermal fluctuations on the stability of membrane-like self-assembled phase with in-plane square order. Surprisingly, the fluctuations are shown to enhance the stability of this quasi-2D phase with respect to transition to alternative 3D structures.4 pages, 2 figures, typo correctedSoft Condensed Mattertext
