Web7 okt. 2024 · Using a modified Cellular Potts Model algorithm that allows rapid thermalization of extensive systems, we numerically explore the order-disorder transition of monodisperse, two-dimensional cellular systems driven by thermal agitation. We show that the transition follows most of the predictions of Kosterlitz-Thouless-Halperin-Nelson-Young (KTHNY ... WebIn the 1970's, Kosterlitz, Thouless, Halperin, Nelson and Young developed KTHNY theory which describes melting of 2D systems as the decoupling of pairs of topological defects and predicts an intermediate phase between solid and liquid called the “hexatic-phase”. 38–42 In a solid 2D system, the crystal has long-range orientational order and quasi-long range … reindex outlook files

Web3 okt. 2024 · The KTHNY theory [ 24 – 26] has been validated. Our observation [ 19] of the destruction of the 2D crystal phase caused by anisotropic impurities raises new and interesting questions. In this study [ 19 ], a 2D colloidal crystal-to-glass transition due to ellipsoid impurities is investigated experimentally through video microscopy.

WebA well accepted theory for phase transitions of two-dimensional systems is the KTHNY theory [4{8]. Named after Kosterlitz, Thouless, Halperin, Nelson and Young, it describes the melting of two-dimensional systems with a continuous, second order, defect-mediated phase tran-sition. The KTHNY theory makes predictions on the long WebUsing video microscopy, we investigated melting of a two-dimensional colloidal system, formed by glycerol droplets at the free surface of a nematic liquid crystalline layer. Analyzing different structure correlation functions, we conclude that melting occurs through an intermediate hexatic phase, as predicted by the KosterlitzThouless-Halperin-Nelson …
