SUMMARY:Ivano Basile - Horror vacui: instabilities in scale-separated Casimir compactifications
DESCRIPTION:Speakers: Ivano Basile (Garching\, Max Planck Inst.)\n.\nAbstract: Finding reliable scale-separated vacua with no moduli in the string landscape is a considerable challenge\, yet it is essential to connect string theory to our universe. Among several attempts\, toroidal compactifications supported by fluxes and Casimir energy stand out for their simplicity and degree of parametric control. In particular\, there exist simple such compactifications of eleven-dimensional supergravity leading to non-supersymmetric weakly curved anti-de Sitter solutions in four dimensions. I will show that these solutions are perturbatively (and non-perturbatively) unstable\, and thus do not pertain to bona fide four-dimensional effective field theories.\nLink: Zoom\nAnLy: https://sites.google.com/view/anlystringsandfields\n \n \nhttps://indico.in2p3.fr/event/38238/
