Higher-order analogues of colour-kinematics duality in first-order Yang-Mills Feynman diagrams
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
Colour-kinematics duality is, even at tree level, not manifest from the standard Lagrangian of Yang-Mills theory in that the usual Feynman-diagram expansion does not follow the kin…
Non-relativistic limits of supersymmetric Yang-Mills theory and S-duality
Hyungrok Kim, Joseph Smith
We investigate non-relativistic limits of four-dimensional maximally supersymmetric Yang-Mills theory (4d MSYM) and their relation to the nonperturbative $\operatorname{SL}(2;\math…
Hydrodynamics as cospans of field theories into the BF theory
Simon Jonsson, Hyungrok Kim
Hydrodynamics is based on conservation laws of currents: one starts from the conserved currents of the theory describing the microscopic dynamics, and provides an alternative param…
Emergent fracton strings from covariant bi-form gauge field theory
Erica Bertolini, Hyungrok Kim, Giandomenico Palumbo
We present a covariant field-theoretical framework for a rank-4 tensor gauge field theory describing fractonic string-like objects. We show that the most general quadratic, parity-…
Ersatz gravity and black-hole thermodynamics from Manin gauge theory with noncompact gauge group
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
We show that a three-dimensional Manin gauge theory with gauge group (i.e. Yang-Mills theory, the third-way theory, or the imaginary third-way theo…
Discrete Approximations to Principal Bundles in Abelian Gauge Theory
Leron Borsten, Hyungrok Kim
A -dimensional field theory with a periodic spatial dimension may be approximated by a -dimensional theory with a truncated Kaluza-Klein tower of fields; as ${k\to\in…
Brane Symmetries Revisited: Symmetries of Tensile and Tensionless Branes in Possibly Degenerate Metrics and their Manifestations
Leron Borsten, Mateo Galdeano, Hyungrok Kim
We analyse the symmetries of tensionless and tensile branes moving in a target space with a possibly degenerate metric, with the worldvolume metric remaining nondegenerate. We reco…
-algebraic extensions of non-Lorentzian kinematical Lie algebras, gravities, and brane couplings
Hyungrok Kim
The Newtonian limit of Newton-Cartan gravity relies crucially on the Lie-algebraic central extension to the Galilean algebra, namely the Bargmann algebra. Lie-algebraic central ext…
Localisation with on-shell supersymmetry algebras via the Batalin-Vilkovisky formalism: Localisation as gauge fixing
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
The Batalin-Vilkovisky formalism provides a powerful technique to deal with gauge and global (super)symmetries that may only hold on shell. We argue that, since global (super)symme…
Symmetries Beget Symmetries: Ghostly Higher-Form Symmetries and the Descent Equation
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
Viewed through the lens of the Batalin-Vilkovisky formalism, we demonstrate that higher-form currents with nonzero ghost number also define higher-form symmetries, directly analogo…
Sandwich Construction of Symmetry TFTs for the Centre Symmetries of Chern-Simons, Yang-Mills, and Einstein Gravity
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
We construct symmetry topological field theories (SymTFTs) using the sandwich construction of Pulmann-Ševera-Valach that manifest the centre symmetries of Chern-Simons theory and Y…
Twisted Homotopy Algebras: Supersymmetric Twists, Spontaneous Symmetry Breaking, Anomalies and Localisation
Leron Borsten, Simon Jonsson, Dimitri Kanakaris +1
Twisting and classical background fields are two foundational techniques in supersymmetric quantum field theory, central to developments ranging from the Higgs mechanism to topolog…
Discrete -Form Symmetry and Higher Coulomb Phases
Leron Borsten, Hyungrok Kim
We argue that a field theory with a -form symmetry generically admits, in addition to a Higgs phase and a 'confining' phase, a Coulomb phase in which the infrared…
Duality Anomalies in Linearized Gravity
Leron Borsten, Michael J. Duff, Dimitri Kanakaris +1
Classical linearized gravity admits a dual formulation in terms of a higher-rank tensor field. Proposing a prescription for the instanton sectors of linearized gravity and its dual…
Homotopy Manin Theories: Generalising Third-Way, Yang-Mills and Integrable Sigma Models
Alex S. Arvanitakis, Leron Borsten, Dimitri Kanakaris +1
Manin theories are a class of non-topological deformations of Chern-Simons theories that naturally realise the third-way mechanism and furthermore admit localisation despite not be…
Gravity from AKSZ-Manin theories in two, three, and four dimensions
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
We show that various dynamical gauge theories in two, three and four dimensions, obtained as Manin deformations of topological Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) theor…
Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
Three-dimensional Yang-Mills theory is three-dimensional gravity with background sources
Leron Borsten, Dimitri Kanakaris, Hyungrok Kim
Chern-Simons theory with certain gauge groups is known to be equivalent to a first-order formulation of three-dimensional Einstein gravity with a cosmological constant, where both…
Topological Classification of Symmetry Breaking and Vacuum Degeneracy
Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1
We argue that a general system of scalar fields and gauge fields manifesting vacuum degeneracy induces a principal groupoid bundle over spacetime and that the pattern of spontaneou…
Adjusted Connections I: Differential Cocycles for Principal Groupoid Bundles with Connection
Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1
We develop a new perspective on principal bundles with connection as morphisms from the tangent bundle of the underlying manifold to a classifying dg-Lie groupoid. This groupoid ca…
Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes
Leron Borsten, Simon Jonsson, Hyungrok Kim
Asymptotic observables in quantum field theory beyond the familiar -matrix have recently attracted much interest, for instance in the context of gravity waveforms. Such observab…
Double-Copying Self-Dual Yang-Mills Theory to Self-Dual Gravity on Twistor Space
Leron Borsten, Branislav Jurco, Hyungrok Kim +3
We construct a simple Lorentz-invariant action for maximally supersymmetric self-dual Yang-Mills theory that manifests colour-kinematics duality. We also show that this action doub…
Double Copy from Tensor Products of Metric BV-algebras
Leron Borsten, Branislav Jurco, Hyungrok Kim +3
Field theories with kinematic Lie algebras, such as field theories featuring colour-kinematics duality, possess an underlying algebraic structure known as BV${}^{\color{gray} \blac…
Construction and Application of Adjusted Higher Gauge Theories
Hyungrok Kim
This PhD thesis investigates several aspects of nonabelian higher gauge theories, which appear in many areas of physics, notably string theory and gauged supergravity. We show that…
