DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/63/">Ho
 rror vacui: instabilities in scale-separated Casimir compactifications</a>
 \nby Ivano Basile (Garching\, Max Planck Inst.) as part of AnLy Strings an
 d Fields online seminars\n\n\nAbstract\nFinding reliable scale-separated v
 acua with no moduli in the string landscape is a considerable challenge\, 
 yet it is essential to connect string theory to our universe. Among severa
 l attempts\, toroidal compactifications supported by fluxes and Casimir en
 ergy stand out for their simplicity and degree of parametric control. In p
 articular\, there exist simple such compactifications of eleven-dimensiona
 l supergravity leading to non-supersymmetric weakly curved anti-de Sitter 
 solutions in four dimensions. I will show that these solutions are perturb
 atively (and non-perturbatively) unstable\, and thus do not pertain to bon
 a fide four-dimensional effective field theories.\n
