Cette thèse porte sur l'étude des propriétés mécaniques des membranes cristallines, matériaux bidimensionnels comportant un réseau périodique d'atomes ou de molécules à l'échelle microscopique qui leur confère des propriétés élastiques. Il s'agit de l'un des rares exemples de systèmes bidimensionnels possédant une phase ordonnée stable à grande distance en présence de fluctuations thermiques. Dans celle-ci, les vecteurs normaux à la surface engendrée par la membrane sont fortement corrélés, d'où son nom de phase plate. Ce manuscrit présente une étude des propriétés de la phase plate à l'aide de méthodes du groupe de renormalisation, inspirées notamment du formalisme de l'action effective moyenne. Tout d'abord, en étudiant la structure de la...
