Isolated Critical Points for Scherk-Schwarz Compactifications of M-theory
Zihni Kaan Baykara, Shi Chen, Cumrun Vafa
We consider Scherk-Schwarz compactifications of M-theory (toroidal compactifications with a non-trivial spin structure) in various dimensions and find isolated critical points of t…

Symmetries and M-theory-like Vacua in Four Dimensions
Shi Chen, Damian van de Heisteeg, Cumrun Vafa
Non-geometric flux vacua have recently been revisited, leading to the remarkable discovery of isolated 4D supersymmetric Minkowski vacua. These constructions rely…

Anomaly and invertible field theory with higher-form symmetry: Extended group cohomology
Shi Chen
In the realm of invertible symmetry, the topological approach based on classifying spaces dominates the classification of 't Hooft anomalies and symmetry protected topological phas…
