Vertex Algebras in Higher Dimensions and Globally Conformal Invariant Quantum Field Theory [PDF]

open access: yesCommunications in Mathematical Physics, 2004
We propose an extension of the definition of vertex algebras in arbitrary space-time dimensions together with their basic structure theory. An one-to-one correspondence between these vertex algebras and axiomatic quantum field theory (QFT) with global conformal invariance (GCI) is constructed.

Light scalars on cosmological backgrounds

open access: yesJournal of High Energy Physics, 2018
We study the behaviour of a light quartically self-interacting scalar field ϕ on curved backgrounds that may be described with the cosmological equation state parameter w.

Bosonization in Higher Dimensions via Noncommutative Field Theory

open access: yesPhysical Review Letters, 2006
We propose the bosonization of a many-body fermion theory in D spatial dimensions through a noncommutative field theory on a (2D-1)-dimensional space. This theory leads to a chiral current algebra over the noncommutative space and reproduces the correct perturbative Hilbert space and excitation energies for the fermions.

Smooth 1-Dimensional Algebraic Quantum Field Theories

open access: yes, 2022
This paper proposes a refinement of the usual concept of algebraic quantum field theories (AQFTs) to theories that are smooth in the sense that they assign to every smooth family of spacetimes a smooth family of observable algebras.

Global anomalies in 8d supergravity

open access: yesJournal of High Energy Physics, 2022
We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups Ω 9 spin BG $$ {\varOmega}_9^{\mathrm{spin}}(BG) $$ which we determine by ...

Constraining conformal field theory with higher spin symmetry in four dimensions [PDF]

open access: yesNuclear Physics B, 2013
We analyze the constraints on the general form and the singularity structure of the correlation functions of the symmetric, traceless and conserved stress-energy tensor implied by conformal invariance and higher spin symmetry in four dimensions. In particular, we show that all these correlation functions will have at most double pole singularities.

Odd dimensional nonlocal Liouville conformal field theories

open access: yesJournal of High Energy Physics, 2022
We construct Euclidean Liouville conformal field theories in odd number of dimensions. The theories are nonlocal and non-unitary with a log-correlated Liouville field, a Q $$ \mathcal{Q} $$ -curvature background, and an exponential Liouville-type ...

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

open access: yesJournal 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.

Index Theory for Short-Ranged Fields in Higher Dimensions

open access: yesJournal of Functional Analysis, 1994
Let \(M\) be a noncompact Riemannian spin manifold of even dimension with a warped end. This means that there exist a compact Riemannian manifold \((N,d\sigma)\) and a compact set \(K_ 0 \subset M\) such that \(M\setminus K_ 0\) is isometric to the product \((0,\infty) \times N\) which is equipped with the warped product metric \(dr^ 2 + f^ 2(r) d ...
