Consistency of Higgsplosion in localizable QFT [PDF]
Physics Letters B, 2019 We show that large n-particle production rates derived in the semiclassical Higgsplosion limit of scalar field theoretical models with spontaneous symmetry breaking, are consistent with general principles of localizable quantum field theory. The strict localizability criterium of Jaffe defines quantum fields as operator-valued distributions acting on ...

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

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 ...

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

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.

Quantum Information in Relativity: The Challenge of QFT Measurements [PDF]
Entropy, 2021 Proposed quantum experiments in deep space will be able to explore quantum information issues in regimes where relativistic effects are important. In this essay, we argue that a proper extension of quantum information theory into the relativistic domain ...
