Landau-Ginzburg description of an exceptional $N = 1$ minimal model

Yu Nakayama, Andrei Katsevich, Igor R. Klebanov +1

The $N = 1$ superconformal minimal model with $m = 12$ and the exceptional modular invariant $(E_{6}, D_{8})$ is the unitary minimal model of the super- $W_{3}$ algebra. We propose it…

$N = 2$ 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 $k^{th}$ $N = 2$ 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 ( $∣ q ∣ < 1$ ) if and only if the arithmetic coefficients $δ (ν)$ 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…
