Twists and Gorms and Antifields, oh my!
Alex S. Arvanitakis
I define topological twists of supersymmetric field theories in the case when the supercharges involved obey an ``open'' algebra. Using the Batalin-Vilkovisky field-antifield forma…
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…
On topological defects in Chern-Simons theory
Alex S. Arvanitakis, Lewis T. Cole, Saskia Demulder +1
We construct a new class of topological surface defects in Chern-Simons theory with non-compact, non-Abelian gauge groups. These defects are characterized by isotropic subalgebras…
Localisation without supersymmetry: towards exact results from Dirac structures in 3D gauge theory
Alex S. Arvanitakis, Dimitri Kanakaris
We show, by introducing purely auxiliary gluinos and scalars, that the quantum path integral for a class of 3D interacting non-supersymmetric gauge theories localises. The theories…
Brane wrapping, AKSZ sigma models, and QP manifolds
Alex S. Arvanitakis, David Tennyson
We introduce a technique to realise brane wrapping and double dimensional reduction in the context of AKSZ topological sigma models and also in their target spaces, which are sympl…
Topological defects as lagrangian correspondences
Alex S. Arvanitakis
Topological defects attract much recent interest in high-energy and condensed matter physics because they encode (non-invertible) symmetries and dualities. We study codimension-1 t…
Unifying Approaches to Chiral Bosons
Alex S. Arvanitakis, Lewis T. Cole, Ondrej Hulik +2
Chiral bosons, or self-dual p-form fields, are ubiquitous in string theoretic contexts but are challenging to treat. Lagrangian constructions invariably introduce a complexity be i…
Formal exponentials and linearisations of QP-manifolds
Alex S. Arvanitakis
We define formal exponential maps for any graded manifold as maps from the formal tangent bundle (that we also define) into the graded manifold. We show that each such map uniquely…
Romans massive QP manifolds
Alex S. Arvanitakis, Emanuel Malek, David Tennyson
We introduce QP manifolds that capture the generalised geometry of type IIA string backgrounds with Ramond-Ramond fluxes and Romans mass. Each of these is associated to a BPS brane…
A QP perspective on topology change in Poisson-Lie T-duality
Alex S. Arvanitakis, Chris D. A. Blair, Daniel C. Thompson
We describe topological T-duality and Poisson-Lie T-duality in terms of QP (differential graded symplectic) manifolds and their canonical transformations. Duality is mediated by a…
Brane current algebras and generalised geometry from QP manifolds
Alex S. Arvanitakis
We construct a Poisson algebra of brane currents from a QP-manifold (alias symplectic -algebroid), and show their Poisson brackets take a universal geometric form. This g…
Homotopy Transfer and Effective Field Theory I: Tree-level
Alex S. Arvanitakis, Olaf Hohm, Chris Hull +1
We use the dictionary between general field theories and strongly homotopy algebras to provide an algebraic formulation of the procedure of integrating out of degrees of freedom in…
Generalising Courant algebroids to M-theory
Alex S. Arvanitakis
We introduce M-theoretic generalisations of the notion of (exact) Courant algebroid, and summarise their connections to generalised geometry, U-duality, and the physics of strings,…
The -algebra of the S-matrix
Alex S. Arvanitakis
We point out that the one-particle-irreducible vacuum correlation functions of a QFT are the structure constants of an -algebra, whose Jacobi identities hold whenever the…
Brane Wess-Zumino terms from AKSZ and exceptional generalised geometry as an -algebroid
Alex S. Arvanitakis
We reinterpret the generalised Lie derivative of M-theory generalised geometry as hamiltonian flow on a graded symplectic supermanifold. The hamiltonian acts as the nilpotent…
The Exceptional Sigma Model
Alex S. Arvanitakis, Chris D. A. Blair
We detail the construction of the exceptional sigma model, which describes a string propagating in the "extended spacetime" of exceptional field theory. This is to U-duality as the…
Type II strings are Exceptional
Alex S. Arvanitakis, Chris D. A. Blair
We construct the exceptional sigma model: a two-dimensional sigma model coupled to a supergravity background in a manifestly (formally) -covariant manner. This formulatio…
Twistor description of spinning particles in AdS
Alex S. Arvanitakis, Alec E. Barns-Graham, Paul K. Townsend
The two-twistor formulation of particle mechanics in D-dimensional anti-de Sitter space for D=4,5,7, which linearises invariance under the AdS isometry group Sp(4;K) for K=R,C,H, i…
A Weyl-invariant action for chiral strings and branes
Alex S. Arvanitakis
We introduce a sigma model lagrangian generalising a number of new and old models which can be thought of as chiral, including the Schild string, ambitwistor strings, and the recen…
Black hole thermodynamics, stringy dualities and double field theory
Alex S. Arvanitakis, Chris D. A. Blair
We discuss black hole thermodynamics in the manifestly duality invariant formalism of double field theory (DFT). We reformulate and prove the first law of black hole thermodynamics…
Anti-de Sitter particles and manifest (super)isometries
Alex S. Arvanitakis, Alec E. Barns-Graham, Paul K. Townsend
Starting from the classical action for a spin-zero particle in a D-dimensional anti-Sitter (AdS) spacetime, we recover the Breitenlohner-Freedman bound by quantization. For D=4,5,7…
Worldline CPT and massless supermultiplets
Alex S. Arvanitakis, Luca Mezincescu, Paul K. Townsend
The action for a massless particle in 4D Minkowski space has a worldline time-reversing symmetry corresponding to CPT invariance of the quantum theory. The analogous symmetry of th…
Pauli-Lubanski, Supertwistors, and the Superspinning Particle
Alex S. Arvanitakis, Luca Mezincescu, Paul K. Townsend
We present a novel construction of the super-Pauli-Lubanski pseudo-vector for 4D supersymmetry and show how it arises naturally from the spin-shell constraints in the supertwistor…
Higher spins from Nambu-Chern-Simons theory
Alex S. Arvanitakis
We propose a new theory of higher spin gravity in three spacetime dimensions. This is defined by what we will call a Nambu-Chern-Simons (NCS) action; this is to a Nambu 3-algebra a…
