In this work two different kinds of solitons are examined. The first are vortices in exciton-polariton Bose-Einstein condensates. Exciton-polariton condensates are a novel state of matter whose peculiar properties, among which very high spatio-temporal coherence, nearly frictionless flow, non-equilibrium, are dramatically influenced by the presence and behaviour of vortices. The second are gravitational instantons, Riemannian manifolds which are exact solutions of Euclidean Einstein equations in four dimensions. According to a recent and innovative proposal, known as the geometric models of matter framework, elementary particles are to be modelled by four-dimensional manifolds. Within this framework, asymptotically locally flat gravitational instantons are considered in this work as candidates for the description of multi-particle systems.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848420902\"\u003e\u003ch3\u003eVortex Dynamics in Polariton Condensates and Geometrical Models of Matter\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783848420902","offer_id":39457340457053,"sku":"9783848420902","price":76.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c22544ee-e3c0-4632-af59-5b9eb5ea0b48.jpg?v=1772866963","url":"https:\/\/shop.autorenwelt.de\/products\/solitons-and-matter-vortex-dynamics-in-polariton-condensates-and-geometrical-models-of-matter-von-guido-franchetti","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
