[Le paysage des vides et la Cosmologie de la Théorie des Cordes]
Il est généralement accepté que la théorie des cordes contient un paysage de 10500 solutions de vide avec des propriétés qui ressemblent à celles de notre Univers. L'existence de ces vides peut être utilisée dans un raisonnement anthropique pour expliquer certains des problèmes les plus ardus en cosmologie et en physique des hautes énergies : ceux de la constante cosmologique, de la hiérarchie et de la platitude du potentiel inflationnaire. Nous expliquerons la construction de ces vides, en insistant sur les défis posés par la construction des vides avec une constante cosmologique positive.
String Theory is believed to have a landscape of 10500 vacua with properties that resemble those of our Universe. The existence of these vacua can be combined with anthropic reasoning to explain some of the hardest problems in cosmology and high-energy physics: the cosmological constant problem, the hierarchy problem, and the un-natural almost-flatness of the inflationary potential. We will explain the construction of these vacua, focusing on the challenges of obtaining vacua with a positive cosmological constant.
