Gauging non-invertible symmetries: topological interfaces and generalized orbifold groupoid in 2d QFT [PDF]
Journal of High Energy Physics, 2023 Gauging is a powerful operation on symmetries in quantum field theory (QFT), as it connects distinct theories and also reveals hidden structures in a given theory.

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.

Wilson loop in general representation and RG flow in 1D defect QFT [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 The generalized Wilson loop operator interpolating between the supersymmetric and the ordinary Wilson loop in N=4 SYM theory provides an interesting example of renormalization group flow on a line defect: the scalar coupling parameter ζ has a non-trivial

Thermalization and chaos in a 1+1d QFT [PDF]
Journal of High Energy Physics, 2022 We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...

Non-perturbative renormalization for the neural network-QFT correspondence [PDF]
Machine Learning: Science and Technology, 2021 In a recent work (Halverson et al 2021 Mach. Learn.: Sci. Technol. 2 035002), Halverson, Maiti and Stoner proposed a description of neural networks (NNs) in terms of a Wilsonian effective field theory.

Journal of High Energy Physics, 2021 We explore the correspondence between geometric function theory (GFT) and quantum field theory (QFT). The crossing symmetric dispersion relation provides the necessary tool to examine the connection between GFT, QFT, and effective field theories (EFTs ...

Emergent gravity as the eraser of anomalous gauge boson masses, and QFT-GR concord [PDF]
General Relativity and Gravitation, 2021 In the same base setup as Sakharov’s induced gravity, we investigate emergence of gravity in effective quantum field theories (QFT), with particular emphasis on the gauge sector in which gauge bosons acquire anomalous masses in proportion to the ...

Proof of the universal density of charged states in QFT [PDF]
Journal of High Energy Physics, 2021 We prove a recent conjecture by Harlow and Ooguri concerning a universal formula for the charged density of states in QFT at high energies for global symmetries associated with finite groups. An equivalent statement, based on the entropic order parameter

QFT without infinities and hierarchy problem [PDF]
Nuclear Physics B, 2021 The standard way to do computations in Quantum Field Theory (QFT) often results in the requirement of dramatic cancellations between contributions induced by a"heavy"sector into the physical observables of the"light"(or low energy) sector - the ...
