Boundary criticality in the Gross-Neveu-Yukawa model at higher orders
Oleksandr Diatlyk, Simone Giombi, Zimo Sun
We extend the study of boundary criticality in the Gross-Neveu-Yukawa universality class beyond leading order. Using the hyperbolic space formulation of boundary conformal field th…
Extraordinary Surface Criticalities for Interacting Fermions
Oleksandr Diatlyk, Zimo Sun, Yifan Wang
Interacting fermions exhibit a rich landscape of surface defects and associated critical phenomena. We investigate novel surface critical behavior in the three-dimensional Gross-Ne…
Sphere free energy of scalar field theories with cubic interactions
Simone Giombi, Elizabeth Himwich, Andrei Katsevich +2
The dimensional continuation approach to calculating the free energy of -dimensional Euclidean CFT on the round sphere has been used to develop its expansion for a…
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…
Ginzburg-Landau description of a class of non-unitary minimal models
Andrei Katsevich, Igor R. Klebanov, Zimo Sun
It has been proposed that the Ginzburg-Landau description of the non-unitary conformal minimal model is provided by the Euclidean theory of two real scalar fields with thi…
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 $Ï\rig…
