Higher-form entanglement asymmetry. Part I. The limits of symmetry breaking
Entanglement asymmetry is a relative entropy that faithfully diagnoses symmetry breaking in quantum states, possibly within a spatial subregion. In this work, we extend such framework to higher-form…

Asymptotically (un)safe scattering amplitudes from scratch: a deep dive into the IR jungle
We compute leading order quantum gravity contributions to a simple scalar scattering amplitude in Asymptotic Safety. Our model admits an analytic treatment so that several subtleties can be analysed.…

Modified Abelian Gauge Theories
The topological properties of field configurations in gauge theory contain important data about the (generalized) global symmetries of the theory as well as potential inconsistencies in the form of…

Geometric QCD II: The Confining Twistor String and Meson Spectrum
We present a local, asymptotically free solution of the planar Makeenko--Migdal loop equations in the continuum limit with full Lorentz invariance. The solution is constructed by quantizing internal…

Self-duality of massless scalar three-point amplitudes
We prove that off-shell massless scalar three-point Feynman integrals are self-dual under Fourier transformation. This implies that a momentum space integral can be expressed as the position space…

Thou shalt not tunnel: Complex instantons and tunneling suppression in deformed quantum mechanics
The quantization of the Seiberg-Witten curve of N=2 super Yang-Mills theory leads to a deformation of one-dimensional quantum mechanics with unconventional behavior. Most notably, quantum…

Metastrings, Metaparticles and Black Hole Thermodynamics: On the Road Towards a Non-singular Black Hole Remnant
We investigate the thermodynamic evolution and endpoint of black hole evaporation in the framework of metastring theory and its particle excitations, the metaparticles. Metaparticles arise as zero…

D-instanton Effects on a D3-brane
It has been proposed by Sen that the D-instanton effects in string theory can be systematically determined through the framework of open-closed string field theory. We apply the latter formalism to…

Maxwell kinematical algebras and 3D gravities
In this paper, we present a Maxwell extension of kinematical Lie algebras by promoting the contraction method underlying the Bacry and Lévy-Leblond cube to a semigroup expansion framework. Within…

Notes on LSZ, i epsilon Prescriptions and Perturbation Theory, in QFT and Cosmology
We review the original argument of Lehmann et al (LSZ) that relates the flat space S-matrix to the correlation function of field operators and clarify some confusing issues. Next we discuss the…

Duality symmetry and dynamics on finite null boundaries
In this work, we derive a set of boost-weighted w functionals of the metric, with w∈\2,1,0,-1,-2\, which transform semi-covariantly under the action of the near-horizon symmetry group. In…

HTEE vs. Pseudo-Entropy in Magnetic Fields
We compare the holographic timelike entanglement entropy with the pseudo-entropy arising from a two-qubit quantum mechanical system. In this model, we consider transitions from an initial thermal…

Correlator-Level Verification of Mass and Current Maps in Abelian Chern-Simons Dualities
