The phase of de Sitter higher spin gravity
Simone Giombi, Zimo Sun
The one-loop Euclidean partition function on the sphere is known to exhibit a nontrivial phase for massless fields of spin greater than one. Such a phase appears to be in tension w…

Towards a Quintic Ginzburg-Landau Description of the Minimal Model
Andrei Katsevich, Igor R. Klebanov, Zimo Sun +1
We discuss dimensional continuation of the massless scalar field theory with the interaction term. It preserves the so-called symmetry, which acts by $ϕ\right…

Higher loops in AdS: applications to boundary CFT
Simone Giombi, Zimo Sun
The Euclidean Anti-de Sitter (AdS) space provides a natural framework for studying boundary conformal field theory (BCFT). We analyze the conformal boundary conditions of the criti…
