20.500.12556/RUL-171237 Continuous symmetry breaking and complexity of biological membranes We consider domain-type patterns in biological membranes that possess an in-plane membrane order. Domains are inseparably linked to topological defects, and many features related to them can be guessed based on universal topological arguments. However, much more complex membrane patterns are typically observed. As possible generators of such configurations, we analyze two relatively simple and universal phenomena. Both are based on continuous symmetry breaking (CSB), which manifests ubiquitously in all branches of physics. We present the Imry–Ma argument which, in addition to CSB, requests the presence of uncorrelated random-field-type disorder. Next, we discuss the Kibble–Zurek mechanism. In addition to CSB it considers dynamical slowing when a relevant phase transition is approached. These approaches were originally introduced in magnetism and cosmology, respectively. We adapt them to effectively two-dimensional membranes and discuss their potential role in membrane structure formation. domains continuous symmetry breaking topological defects disorder true false true Angleški jezik Ni določen Članek v reviji 2025-08-20 14:20:23 2025-08-20 14:20:24 2025-08-21 04:02:33 0000-00-00 00:00:00 2025 0 0 18 str. iss. 8, art. 737 Vol. 15 Jul. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-08-20 577 2073-4352 10.3390/cryst15080737 246093315 crystals-15-00737.pdf crystals-15-00737.pdf 1 50865D40DE7D7EFF577602477EB8FA36 a21d8b979f28db827a200834acfd552dcc41fb5b50d94c81a287101af019c18c 3353fe16-7dc0-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214405 https://www.mdpi.com/2073-4352/15/8/737 1 f347099a-7dbf-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214404 Zdravstvena fakulteta Fakulteta za elektrotehniko 0 0 0
