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…
Hilbert space of Quantum Field Theory in de Sitter spacetime
Joao Penedones, Kamran Salehi Vaziri, Zimo Sun
We study the decomposition of the Hilbert space of quantum field theory in dimensional de Sitter spacetime into Unitary Irreducible Representations (UIRs) of its isometry g…
A radial variable for de Sitter two-point functions
Manuel Loparco, Jiaxin Qiao, Zimo Sun
We introduce a "radial" two-point invariant for quantum field theory in de Sitter (dS) analogous to the radial coordinate used in conformal field theory. We show that the two-point…
The phase of charged Nariai solutions
Victor Ivo, Zimo Sun
In this note, we compute the phase of the one-loop Euclidean path integral around charged Nariai solutions in 4 dimensions, including both metric and gauge field fluctuations. Thes…
Ginzburg-Landau Description and Emergent Supersymmetry of the Minimal Model
Igor R. Klebanov, Vladimir Narovlansky, Zimo Sun +1
A pair of the 2D non-unitary minimal models is known to be equivalent to a variant of the minimal model. We discuss the RG flow from this model to another non-un…
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…
