Landau-Ginzburg description of an exceptional minimal model
Yu Nakayama, Andrei Katsevich, Igor R. Klebanov +1
The superconformal minimal model with and the exceptional modular invariant is the unitary minimal model of the super- algebra. We propose it…
RG flows, Non-Invertible Symmetries and Matrix Factorisations
Federico Ambrosino, Matthias R. Gaberdiel, Yu Nakayama
We study the behaviour of the topological defect lines of the minimal models that are preserved by the least relevant perturbation to first order. It is u…
Interior zeros of supersymmetric indices
Yu Nakayama, Tadashi Okazaki
A supersymmetric index has interior zeros () if and only if the arithmetic coefficients underlying the supersymmetric zeta function grow exponentially at a rate set b…
Holographic spectral functions for Sasaki-Einstein 5-manifolds
Yu Nakayama, Tadashi Okazaki
We investigate holographic spectral functions for general Sasaki-Einstein 5-manifolds dual to four-dimensional superconformal field theories, including supersymmetric indices, supe…
ADE triality via (non-)invertible symmetry gauging
Takahilo Tanaka, Yu Nakayama
It is long known that A-series minimal models and D-series minimal models are exchanged by gauging the invertible symmetry. More recently, it has been shown that A-s…
c-Theorem and improvement in non-compact conformal field theories
Nanami Nakamura, Yu Nakayama
Energy-momentum tensor in general conformal field theories have improvement ambiguity and it can affect the argument in deriving -theorem. While the derivation of Zamolodchikov'…
Is chiral supersymmetry emanant or emergent?
Yu Nakayama
The extended Majorana Nicolai model is one of the simplest models of supersymmetry realized on a fermionic chain in dimensions. Within a certain parameter region, the extende…
Infinitely many new renormalization group flows between Virasoro minimal models from non-invertible symmetries
Takahilo Tanaka, Yu Nakayama
Based on the study of non-invertible symmetries, we propose there exist infinitely many new renormalization group flows between Virasoro minimal models $\mathcal{M}(kq + I, q) \to\…
Convexity restoration from hairy black hole in Einstein-Maxwell-charged scalar system in AdS
Takaaki Ishii, Yu Nakayama
In the Einstein-Maxwell-charged scalar system with a negative cosmological constant in arbitrary dimensions higher than three, there exists a horizonless charged soliton solution,…
