Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes

open access: yesJournal of High Energy Physics
Asymptotic observables in quantum field theory beyond the familiar S-matrix have recently attracted much interest, for instance in the context of gravity waveforms.

Crossed products, conditional expectations and constraint quantization

open access: yesNuclear Physics B
Recent work has highlighted the importance of crossed products in correctly elucidating the operator algebraic approach to quantum field theories. In the gravitational context, the crossed product simultaneously promotes von Neumann algebras associated ...

Open string field theory in lightcone gauge

open access: yesJournal of High Energy Physics
We study covariant open bosonic string field theory in lightcone gauge. When lightcone gauge is well-defined, we find two results. First, the vertices of the gauge-fixed action consist of Mandelstam diagrams with stubs covering specific portions of the ...

Off-shell color-kinematics duality from codifferentials

open access: yesJournal of High Energy Physics
We examine the color-kinematics duality within the BV formalism, highlighting its emergence as a feature of specific gauge-fixed actions. Our goal is to establish a general framework for studying the duality while investigating straightforward examples ...
