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…
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…
Homotopy representations of extended holomorphic symmetry in holomorphic twists
Simon Jonsson, Hyungrok Kim, Charles Alastair Stephen Young
We argue that holomorphic twists of supersymmetric field theories naturally come with a symmetry -algebra that nontrivially extends holomorphic symmetry. This symmetry ac…
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…
