CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe study the chaotic dynamics which occurs in a nematic liquid crystal film during the director reorientation induced by an intense optical field. We show the presence of intermittency in the fluctuations of the transmitted Light intensity polarized perpendicularly to the incident beam. The intermittency can safely be described by the multifractal geometry, and, in this framework, we present a simple heuristic model for the phenomenon.

| Abstract: | We study the chaotic dynamics which occurs in a nematic liquid crystal film during the director reorientation induced by an intense optical field. We show the presence of intermittency in the fluctuations of the transmitted Light intensity polarized perpendicularly to the incident beam. The intermittency can safely be described by the multifractal geometry, and, in this framework, we present a simple heuristic model for the phenomenon. |
