Universal quadratic field equations via homotopy algebras

Christoph Chiaffrino, Raji Ashenafi Mamade, Barton Zwiebach

We explain how the 'bar-cobar' construction for homotopy algebras reformulates the equations of motion of arbitrary gauge theories as gauge-covariant quadratic equations for an ext…

Color-kinematics duality from an algebra of superforms

Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm +1

Color-kinematics duality states that the kinematic numerators of the cubic tree-level Yang-Mills scattering amplitudes obey the same symmetry properties that the color factors obey…

Yang-Mills kinematic algebra via homotopy transfer from a worldline operator algebra

Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm +1

The homotopy Lie or algebra encoding Yang-Mills theory is the tensor product of a color Lie algebra with the kinematic algebra. We derive this $C_{\infty}…

Off-Shell Quantum Mechanics as Factorization Algebras on Intervals

Christoph Chiaffrino, Noah Hassan, Olaf Hohm

We present, for the harmonic oscillator and the spin- system, an alternative formulation of quantum mechanics that is `off-shell': it is based on classical off-shell c…

Vertex operators for the kinematic algebra of Yang-Mills theory

Roberto Bonezzi, Christoph Chiaffrino, Olaf Hohm

The kinematic algebra of Yang-Mills theory can be understood in the framework of homotopy algebras: the algebra of Yang-Mills theory is the tensor product of the color…

Tree-level Scattering Amplitudes via Homotopy Transfer

Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1

We formalize the computation of tree-level scattering amplitudes in terms of the homotopy transfer of homotopy algebras, illustrating it with scalar and Yang-Mills theory. Th…

Weakly Constrained Double Field Theory as the Double Copy of Yang-Mills Theory

Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1

Weakly constrained double field theory, in the sense of Hull and Zwiebach, captures the subsector of string theory on toroidal backgrounds that includes gravity, -field and dila…

Holography as Homotopy

Christoph Chiaffrino, Talha Ersoy, Olaf Hohm

We give an interpretation of holography in the form of the AdS/CFT correspondence in terms of homotopy algebras. A field theory such as a bulk gravity theory can be viewed as a hom…

Gravity = Yang-Mills

Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1

This essay's title is justified by discussing a class of Yang-Mills-type theories of which standard Yang-Mills theories are special cases but which is broad enough to include gravi…

Weakly constrained double field theory: the quartic theory

Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1

Double field theory was originally introduced as the subsector of closed string field theory on a toroidal background given by the massless fields together with all their massive K…

Gauge invariant double copy of Yang-Mills theory: the quartic theory

Roberto Bonezzi, Christoph Chiaffrino, Felipe Diaz-Jaramillo +1

We give an explicit gauge invariant, off-shell and local double copy construction of gravity from Yang-Mills theory to quartic order. To this end we use the framework of homotopy a…

Homological Quantum Mechanics

Christoph Chiaffrino, Olaf Hohm, Allison F. Pinto

We provide a formulation of quantum mechanics based on the cohomology of the Batalin-Vilkovisky (BV) algebra. Focusing on quantum-mechanical systems without gauge symmetry we intro…

QFT with Stubs

Christoph Chiaffrino, Ivo Sachs

The BV-Laplacian in quantum field theory is singular, by construction, but can be regularized by deforming the classical BV-action. Taking inspiration from string theory we des…

Gauge Invariant Perturbation Theory via Homotopy Transfer

Christoph Chiaffrino, Olaf Hohm, Allison F. Pinto

We show that the perturbative expansion of general gauge theories can be expressed in terms of gauge invariant variables to all orders in perturbations. In this we generalize techn…

Classical Open String Amplitudes and Boundary String Field Theory

Christoph Chiaffrino, Ivo Sachs

Abstract: We show that boundary string field theory realizes the minimal model of open string field theory. More precisely, we observe that the expansion of the (co)homological vec…
