E 8 instantons on type-A ALE spaces and supersymmetric field theories

Journal of High Energy Physics, 2017
We consider the 6d superconformal field theory realized on M5-branes probing the E 8 end-of-the-world brane on the deformed and resolved ℂ 2/ℤ k singularity.

Modular Hamiltonian of the scalar in the semi infinite line: dimensional reduction for spherically symmetric regions

Journal of High Energy Physics, 2023
We focus our attention on the one dimensional scalar theories that result from dimensionally reducing the free scalar field theory in arbitrary d dimensions.

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories [PDF]

Journal of High Energy Physics, 2018
A bstractWe consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N=1$$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions.

Topological dualities in the Ising model

, 2021
We relate two classical dualities in low-dimensional quantum field theory: Kramers-Wannier duality of the Ising and related lattice models in $2$ dimensions, with electromagnetic duality for finite gauge theories in $3$ dimensions.

On the Trace Anomaly as a Measure of Degrees of Freedom [PDF]

, 2000
Recent conjectures of the c-theorem in four and higher dimensions have suggested that the coefficient of the Euler characteristic in the trace anomaly could measure the degrees of freedom in field theory and decrease along the renormalization-group flow.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Field redefinitions can be nonlocal

Journal of High Energy Physics
We revisit the lore establishing the allowed space of field redefinitions and show that there are essentially no restrictions. Our conclusions hold to all orders in perturbation theory and for any dispersion relation. Field redefinitions can be nonlocal,

Nonperturbative bounds on scattering of massive scalar particles in d ≥ 2

Journal of High Energy Physics, 2022
We study two-to-two scattering amplitudes of a scalar particle of mass m. For simplicity, we assume the presence of ℤ2 symmetry and that the particle is ℤ2 odd.

Weyl-Invariant Higher Curvature Gravity Theories in n Dimensions [PDF]

, 2012
We study the particle spectrum and the unitarity of the generic n-dimensional Weyl-invariant quadratic curvature gravity theories around their (anti-)de Sitter [(A)dS] and flat vacua.
