Fifth forces and broken scale symmetries in the Jordan frame [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We study the origin of fifth forces in scalar-tensor theories of gravity in the so-called Jordan frame, where the modifications to the gravitational sector are manifest.

Gravity, duality and conformal symmetry [PDF]
Proceedings of the Royal Society A, 2022 The (4,0) supermultiplet in six dimensions contains a fourth-rank tensor gauge field with the symmetries of the Riemann tensor and is superconformal, with 32+32 supersymmetries. Dimensional reduction on a circle gives the five dimensions N=8 supergravity

Conformal little Higgs models [PDF]
Physical Review D, 2023 Little Higgs models address the hierarchy problem by identifying the SM Higgs doublet as pseudo-Nambu--Goldstone bosons (pNGB) arising from global symmetries with collective breakings.

Generalized symmetries and Noether’s theorem in QFT [PDF]
Journal of High Energy Physics, 2022 We show that generalized symmetries cannot be charged under a continuous global symmetry having a Noether current. Further, only non-compact generalized symmetries can be charged under a continuous global symmetry.

From CFTs to theories with Bondi-Metzner-Sachs symmetries: Complexity and out-of-time-ordered correlators [PDF]
Physical Review D, 2022 We probe the contraction from 2 d relativistic CFTs to theories with Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, using diagnostics of quantum chaos. Starting from an Ultrarelativistic limit on a relativistic scalar

Pseudo-Conformal Sound Speed in the Core of Compact Stars [PDF]
Symmetry, 2022 By implementing the putative “hadron-quark continuity" conjectured in QCD in terms of skyrmion-half-skyrmion topological change in an effective field theory for dense matter, we argue that (quasi-)baryons could “masquerade" deconfined quarks in the ...

Analytic bootstrap for the localized magnetic field
Journal of High Energy Physics, 2023 We study the two-point function of local operators in the critical O(N) model in the presence of a magnetic field localized on a line. We use a recently developed conformal dispersion relation to compute the correlator at first order in the ϵ-expansion ...

Improved Noether’s theorem for spacetime symmetries [PDF]
Physical Review D, 2022 We exploit an ambiguity somewhat hidden in Noether’s theorem to derive systematically, for relativistic field theories, the stress-energy tensor’s improvement terms that are associated with additional spacetime symmetries beyond translations.

Yukawa interactions at large charge
Journal of High Energy Physics, 2022 We extend the fixed-charge semiclassical method by computing anomalous dimensions of fixed-charge scalar operators in models with Yukawa interactions. In particular, we discuss the Nambu-Jona-Lasinio-Yukawa theory as well as an asymptotically safe gauge ...

Conformal (p, q) supergeometries in two dimensions [PDF]
Journal of High Energy Physics, 2022 We propose a superspace formulation for conformal ( p , q ) supergravity in two dimensions as a gauge theory of the superconformal group OSp_0( p |2; ℝ ) × OSp_0( q |2; ℝ ) with a flat connection.
