Poincaré, Scale and Conformal Symmetries: Gauge Perspective and Cosmological Ramifications [PDF]

open access: yes, 2016
In the first part of the thesis we focus on local symmetries. We review a self-consistent framework that we employed in order to discuss the dynamics of the theories of interest. Its merit lies in that we can make the symmetry group act internally and thus be effectively separated from coordinate transformations.

Spacetime Symmetries and Conformal Data in the Continuous Multiscale Entanglement Renormalization Ansatz [PDF]

open access: yesPhysical Review Letters, 2017
The generalization of the multi-scale entanglement renormalization ansatz (MERA) to continuous systems, or cMERA [Haegeman et al., Phys. Rev. Lett, 110, 100402 (2013)], is expected to become a powerful variational ansatz for the ground state of strongly interacting quantum field theories. In this paper we investigate, in the simpler context of Gaussian

Non-Lorentzian RG flows and supersymmetry

open access: yesJournal 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

Broken conformal symmetry and hadronic scaling [PDF]

open access: yesPhysics Letters B, 1973
Abstract High energy, large momentum transfer hadronic reactions are studied in the framework of broken conformal symmetry. Hadrons lie on almost linear Regge trajectories. Inclusive cross section scale as ∼s −2 ( q 2 T s) −4 . Large rates of heavy particle production are predicted.

Scaling and conformal symmetries for plane gravitational waves [PDF]

open access: yesJournal of Mathematical Physics, 2020
The isometries of an exact plane gravitational wave are symmetries for both massive and massless particles. Their conformal extensions are, in fact, chrono-projective transformations {introduced earlier by Duval et al. [Classical Quantum Gravity 3, 461 (1986); Classical Quantum Gravity 32(17), 175006 (2015)]} and are symmetries for massless particles ...

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 ...

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 ...

Scale-invariant breaking of conformal symmetry [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2015
Known examples of unitary relativistic scale but not conformal-invariant field theories (SFTs) can be embedded into conventional conformal field theories (CFTs). We show that any SFT which is a subsector of a unitary CFT is a free theory. Our discussion applies to an arbitrary number of spacetime dimensions and explains triviality of known SFTs in four

Narain CFTs and quantum codes at higher genus

open access: yesJournal of High Energy Physics, 2023
Code CFTs are 2d conformal field theories defined by error-correcting codes. Recently, Dymarsky and Shapere generalized the construction of code CFTs to include quantum error-correcting codes. In this paper, we explore this connection at higher genus. We
