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…
Solitonic symmetry as non-invertible symmetry: cohomology theories with TQFT coefficients
Shi Chen, Yuya Tanizaki
Originating from the topology of the path-integral target space , solitonic symmetry describes the conservation law of topological solitons and the selection rule of defect oper…
Solitonic symmetry beyond homotopy: Invertibility from bordism and noninvertibility from topological quantum field theory
Shi Chen, Yuya Tanizaki
Solitonic symmetry has been believed to follow the homotopy-group classification of topological solitons. Here, we point out a more sophisticated algebraic structure when solitons…
Late-time correlation functions in dS/CFT correspondence
Heng-Yu Chen, Shi Chen, Yasuaki Hikida
We compute the late-time correlation functions on three-dimensional de Sitter spacetime for a higher-spin gravity theory. For this, we elaborate on the formulation to obtain the wa…
