Generalized symmetries and Noether’s theorem in QFT [PDF]

open access: yesJournal 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.

Pseudo-Conformal Sound Speed in the Core of Compact Stars [PDF]

open access: yesSymmetry, 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 ...

Conformal Symmetry as a Template: Commensurate Scale Relations and Physics Renormalization Schemes

open access: green, 1999
Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the "generalized Crewther relation", which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum rules to measurements of the e+ e- annihilation cross section.

Conformal Symmetry as a Template:Commensurate Scale Relations and Physical Renormalization Schemes [PDF]

open access: bronze, 1999
Commensurate scale relations are perturbative QCD predictions which relate observable to observable at fixed relative scale, such as the ''generalized Crewther relation'', which connects the Bjorken and Gross-Llewellyn Smith deep inelastic scattering sum rules to measurements of the e{sup +}e{sup {minus}} annihilation cross section.

Improved Noether’s theorem for spacetime symmetries [PDF]

open access: yesPhysical 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.

Conformal (p, q) supergeometries in two dimensions [PDF]

open access: yesJournal 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.

Analytic bootstrap for the localized magnetic field

open access: yesJournal 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 ...

Topology change, emergent symmetries and compact star matter [PDF]

open access: yesAAPPS Bulletin, 2021
Topology effects have being extensively studied and confirmed in strongly correlated condensed matter physics. In the limit of large number of colors, baryons can be regarded as topological objects—skyrmions—and the baryonic matter can be regarded as a ...

Yukawa interactions at large charge

open access: yesJournal 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 ...

Cusp in the symmetry energy, speed of sound in neutron stars and emergent pseudo-conformal symmetry [PDF]

open access: yesModern Physics Letters A, 2021
In this paper, we review how the “cusp” predicted in the nuclear symmetry energy generated by a topology change at density [Formula: see text] can have a surprising consequence, so far unrecognized in nuclear physics and astrophysics communities, on the ...
