This paper considers the possibility that, starting from a relativistic Hermitian quantum field
theory in the ultraviolet (UV) regime, and applying a nonperturbative renormalization-group …

A bstract Based on the study of non-invertible symmetries, we propose there exist infinitely
many new renormalization group flows between Virasoro minimal models\(\mathcal …

Abstract Integrable Quantum Field Theories can be solved exactly using bootstrap
techniques based on their elastic and factorisable S-matrix. While knowledge of the …

A bstract We study a novel class of Renormalization Group flows which connect multicritical
versions of the two-dimensional Yang-Lee edge singularity described by the conformal …

It has been proposed that the Ginzburg-Landau description of the non-unitary conformal
minimal model $ M (3, 8) $ is provided by the Euclidean theory of two real scalar fields with …

A bstract A pair of the 2D non-unitary minimal models M (2, 5) is known to be equivalent to a
variant of the M (3, 10) minimal model. We discuss the RG flow from this model to another …

The high-temperature limit of the superconformal index, especially on higher sheets, often
captures useful universal information about a theory. In 4d $\mathcal {N}= 2 …

We study analytical properties and integrable structures of the meson spectrum in large $
N_c $ QCD $ _2 $. We show that the integral equation that determines the masses of the …

A bstract We investigate the fate of the non-supersymmetric Gross-Neveu-Yukawa fixed
point found by Fei et al. in 4− ϵ dimensions with a two-component Majorana fermion …

We describe a novel class of quantum mechanical particle oscillations in both relativistic and
nonrelativistic systems based on PT symmetry and T 2=-1 (relevant for fermions), where P is …
