20.500.12556/RUL-118018 Chirality-enhanced periodic self-focusing of light in soft birefringent media We experimentally and numerically show that chirality can play a major role in the nonlinear optical response of soft birefringent materials, by studying the nonlinear propagation of laser beams in frustrated cholesteric liquid crystal samples. Such beams exhibit a periodic nonlinear response associated with a bouncing pattern for the optical fields, as well as a self-focusing effect enhanced by the chirality of the birefringent material. Our results open new possible designs of nonlinear optical devices with low power consumption and tunable interactions with localized topological solitons. soft matter physics liquid crystals optics fizika mehke snovi tekoči kristali optika true false false Angleški jezik Slovenski jezik Neznano 2020-08-12 15:55:41 2020-08-12 15:55:43 2022-08-30 04:01:04 0000-00-00 00:00:00 2020 0 0 Str. 077801-1-077801-6 iss. 7 Vol. 125 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 0031-9007 10.1103/PhysRevLett.125.077801 24983555 1282575 RAZ_Poy_Guilhem_2020.pdf RAZ_Poy_Guilhem_2020.pdf 1 682D6D432C651413F2E0D96E9742B71C 536e464cfdd863a781c09772c0fde3f1e685ed024ad0189635f98fa111caa840 4c200bef-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=131951 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.077801 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141293 Fakulteta za matematiko in fiziko 0 0 0
