SUMMARY:[Biophysics seminar] Andraž Gnidovec: "Simulating the packing of spherical ellipses"
DESCRIPTION:Packing problems are abundant in nature and are thoroughly researched both experimentally and in numerical models. In particular\, packings of anisotropic\, elliptical particles emerge in models of liquid crystals\, colloids\, as well as granular and jammed matter. While most of these studies deal with packings in Euclidean geometries\, there are many experimental systems where anisotropically shaped particles are confined to a curved surface\, such systems of colloidal rods trapped at the interface of emulsion droplets\, and protein adsorbates on vesicles. \nIn this talk\, I will first present an algorithm we developed to determine overlaps between two spherical ellipses. More generally\, the proposed method allows us to define a continuous contact function that could also be applied to long-range interactions\, however\, the use case as a distance metric must be considered with care. Returning to the main objective of the algorithm\, I will demonstrate its efficiency in packing simulations. I will show the random close packing results for a monodispersed system of hard ellipses and present some challenges in the analysis of the configurations in comparison to the ellipse packings in Euclidean space.\n\n\nThe talk will be in the tea room at the F1 department. It will be simultaneously transmitted online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio\n\n\n\n
