20.500.12556/DiRROS-27765 Reentrant rigidity transition in planar epithelia with volume and area elasticity We find a reentrant columnar-to-squamous rigidity transition in three-dimensional (3D) epithelia, governed by volume and area elasticity. Our model maps to the classic 2D area- and perimeter-elasticity model but, unlike its 2D counterpart, shows compression-induced softening or stiffening, depending on the initial state. The phase diagram reveals floppy states with vanishing shear and in-plane bulk moduli, alongside a lateral-tension-driven discontinuous columnar-to-squamous transition. The critical behavior underlying the emergence of the reentrant transition belongs to the mean-field universality class. biophysics epithelial mechanics rigidity transition phase diagram mehanika epitelija prehod togosti fazni diagram true false true American Physical Society ZDA Angleški jezik Slovenski jezik Neznano 2026-02-24 13:07:40 2026-02-24 13:07:40 2026-02-25 03:50:47 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 19. 2. 2026; str. 068404-1-068404-6 [article no.] 068404 Vol. 136 Feb. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-05-20 2026-01-22 2026-02-12 577 1079-7114 10.1103/ky2j-5nwx 269036291 https://journals.aps.org/prl/abstract/10.1103/ky2j-5nwx 1 6cc0df49-1179-11f1-9cb0-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=40808 RAZ_Sarkar_Tanmoy_2026.pdf RAZ_Sarkar_Tanmoy_2026.pdf 1 88A2EF52176457145D3774CC71252D88 212dd57c3500a37b4f631aa5bbc88686955907b25bf1176122b989fe5fed6033 b75da5ee-1179-11f1-9cb0-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=40809 Institut Jožef Stefan 0 0 0
