Hecke relations among 2d fermionic RCFTs
Journal of High Energy Physics, 2023 Recently, Harvey and Wu proposed a suitable Hecke operator for vector-valued SL(2, ℤ) modular forms to connect the characters of different 2d rational conformal field theories (RCFTs).

Shift operators from the simplex representation in momentum-space CFT
Journal of High Energy Physics, 2023 We derive parametric integral representations for the general n-point function of scalar operators in momentum-space conformal field theory. Recently, this was shown to be expressible as a generalised Feynman integral with the topology of an (n − 1 ...

Magic fermions: Carroll and flat bands
Journal of High Energy Physics, 2023 The Carroll algebra is constructed as the c → 0 limit of the Poincare algebra and is associated to symmetries on generic null surfaces. In this paper, we begin investigations of Carrollian fermions or fermions defined on generic null surfaces. Due to the

Non-Lorentzian RG flows and supersymmetry
Journal of High Energy Physics, 2019 We describe a general process where a non-Lorentzian rescaling of a supersymmetric field theory leads to a scale-invariant fixed point action without Lorentz invariance but where the supersymmetry is preserved or even enhanced. We apply this procedure to

Conformal bootstrap in momentum space at finite volume
Journal of High Energy Physics, 2023 In this paper, we Fourier transform the Wightman function concerning energy and angular momentum on the S D−1 spatial slice in radial quantization in D = 2, 3 dimensions.

Anomaly-free scale symmetry and gravity [PDF]
, 2022 In this Letter, we address the question of whether the conformal invariance can be considered as a global symmetry of a theory of fundamental interactions. To describe Nature, this theory must contain a mechanism of spontaneous breaking of the scale symmetry. Besides that, the fundamental theory must include gravity, whereas all known extensions of the

Bootstrapping conformal QED3 and deconfined quantum critical point
Journal of High Energy Physics, 2022 We bootstrap the deconfined quantum critical point (DQCP) and 3D Quantum Electrodynamics (QED3) coupled to N f flavors of two-component Dirac fermions. We show the lattice and perturbative results on the SO(5) symmetric DQCP are excluded by the bootstrap

Fake Conformal Symmetry in Unimodular Gravity [PDF]
Phys. Rev. D 94, 044032 (2016), 2016 We study Weyl symmetry (local conformal symmetry) in unimodular gravity. It is shown that the Noether currents for both Weyl symmetry and global scale symmetry, identically vanish as in the conformally invariant scalar-tensor gravity. We clearly explain why in the class of conformally invariant gravitational theories, the Noether currents vanish by ...

Dualities between fermionic theories and the Potts model
Journal of High Energy Physics, 2023 We show that a large class of fermionic theories are dual to a q → 0 limit of the Potts model in the presence of a magnetic field. These can be described using a statistical model of random forests on a graph, generalizing the (unrooted) random forest ...

The Gross-Neveu-Yukawa archipelago
Journal of High Energy Physics, 2023 We perform a bootstrap analysis of a mixed system of four-point functions of bosonic and fermionic operators in parity-preserving 3d CFTs with O(N) global symmetry. Our results provide rigorous bounds on the scaling dimensions of the O(N)-symmetric Gross-
