Symmetries in quantum field theory and quantum gravity

D Harlow, H Ooguri - Communications in Mathematical Physics, 2021 - Springer
In this paper we use the AdS/CFT correspondence to refine and then establish a set of old
conjectures about symmetries in quantum gravity. We first show that any global symmetry …

On revolutionizing quantum field theory with Tomita's modular theory

HJ Borchers - Journal of mathematical Physics, 2000 - pubs.aip.org
In the book of Haag [Local Quantum Physics (Springer Verlag, Berlin, 1992)] about local
quantum field theory the main results are obtained by the older methods of C*-and W …

Categorical symmetry and noninvertible anomaly in symmetry-breaking and topological phase transitions

W Ji, XG Wen - Physical Review Research, 2020 - APS
For a zero-temperature Landau symmetry-breaking transition in n-dimensional space that
completely breaks a finite symmetry G, the critical point at the transition has the symmetry G …

Constraints on symmetries from holography

D Harlow, H Ooguri - Physical review letters, 2019 - APS
In this Letter we show that a set of old conjectures about symmetries in quantum gravity hold
within the anti–de Sitter/conformal field theory correspondence. These conjectures are that …

On the independence of local algebras in quantum field theory

SJ Summers - Reviews in Mathematical Physics, 1990 - World Scientific
A review is made of the multitude of different mathematical formalizations of the physical
concept 'two observables (or two systems) are independent'that have been proposed in …

Why there is a field algebra with a compact gauge group describing the superselection structure in particle physics

S Doplicher, JE Roberts - Communications in Mathematical Physics, 1990 - Springer
Given the local observables in the vacuum sector fulfilling a few basic principles of local
quantum theory, we show that the superselection structure, intrinsically determined a priori …

Generalized symmetries and Noether's theorem in QFT

V Benedetti, H Casini, JM Magán - Journal of High Energy Physics, 2022 - Springer
A bstract We show that generalized symmetries cannot be charged under a continuous
global symmetry having a Noether current. Further, only non-compact generalized …

Operator algebras and conformal field theory

F Gabbiani, J Fröhlich - Communications in mathematical physics, 1993 - Springer
We define and study two-dimensional, chiral conformal field theory by the methods of
algebraic field theory. We start by characterizing the vacuum sectors of such theories and …

Modular invariance as completeness

V Benedetti, H Casini, Y Kawahigashi, R Longo… - Physical Review D, 2024 - APS
We review the physical meaning of modular invariance for unitary conformal quantum field
theories in d= 2. For quantum field theory models, while T invariance is necessary for …

Reflected entropy, symmetries and free fermions

P Bueno, H Casini - Journal of High Energy Physics, 2020 - Springer
A bstract Exploiting the split property of quantum field theories (QFTs), a notion of von
Neumann entropy associated to pairs of spatial subregions has been recently proposed …
