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 ...

Conformal Mechanics and the Virasoro Algebra [PDF]

, 1999
We demonstrate that any scale-invariant mechanics of one variable exhibits not only 0+1 conformal symmetry, but also the symmetries of a full Virasoro algebra. We discuss the implications for the adS/CFT correspondence.Comment: 9 pages, LaTeX.

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 ...

Improved Energy-Momentum Currents in Metric-Affine Spacetime [PDF]

, 1992
In Minkowski spacetime it is well-known that the canonical energy-momentum current is involved in the construction of the globally conserved currents of energy-momentum and total angular momentum.

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

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-

A scaling limit for line and surface defects

Journal of High Energy Physics, 2022
We study symmetry-breaking line defects in the Wilson-Fisher theory with O(2N + 1) global symmetry near four dimensions and symmetry-preserving surface defects in a cubic model with O(2N) global symmetry near six dimensions.

Consistency Relations for the Conformal Mechanism [PDF]

, 2013
We systematically derive the consistency relations associated to the non-linearly realized symmetries of theories with spontaneously broken conformal symmetry but with a linearly-realized de Sitter subalgebra.

Renormalization group flows between Gaussian fixed points

Journal of High Energy Physics, 2022
A scalar theory can have many Gaussian (free) fixed points, corresponding to Lagrangians of the form ϕ□ n ϕ. We use the non-perturbative RG to study examples of flows between such fixed points. We show that the anomalous dimension changes continuously in
