Moduli spaces of type II twists
Fabian Hahner
We provide a complete classification of twisting supercharges for type IIA supergravity in a flat background by determining the orbits of square-zero elements in the $\mathcal{N}=(…
Twisting BFSS & IKKT
Fabian Hahner, Natalie M. Paquette
In this note we initiate the study of ``twisted holography'' for the dualities involving the BFSS matrix quantum mechanics and the IKKT matrix model in their …
On square-zero elements in the IIB supersymmetry algebra
Fabian Hahner
We describe the variety of square-zero elements in the (2,0) super Poincaré algebra in ten dimensions, together with its orbit stratification induced by the action of the spin grou…
Higher Symmetries in Twisted Eleven-Dimensional Supergravity
Fabian Hahner, Natalie M. Paquette, Surya Raghavendran
In supersymmetric theories, protected quantities can be reorganized into holomorphic-topological theories by twisting. Recently, it was observed by Jonsson, Kim and Young that resi…
Local superconformal algebras
Fabian Hahner, Surya Raghavendran, Ingmar Saberi +1
Given a supermanifold equipped with an odd distribution of maximal dimension and constant symbol, we construct the formal moduli problem of deformations of the distribution. This m…
Eleven-dimensional supergravity as a Calabi-Yau twofold
Fabian Hahner, Ingmar Saberi
We construct a generalization of Poisson-Chern-Simons theory, defined on any supermanifold equipped with an appropriate filtration of the tangent bundle. Our construction recovers…
Six-dimensional supermultiplets from bundles on projective spaces
Fabian Hahner, Simone Noja, Ingmar Saberi +1
The projective variety of square-zero elements in the six-dimensional minimal supersymmetry algebra is isomorphic to . We use this fact, together…
The Derived Pure Spinor Formalism as an Equivalence of Categories
Chris Elliott, Fabian Hahner, Ingmar Saberi
We construct a derived generalization of the pure spinor superfield formalism and prove that it exhibits an equivalence of dg-categories between multiplets for a supertranslation a…
Perspectives on the pure spinor superfield formalism
Richard Eager, Fabian Hahner, Ingmar Saberi +1
In this note, we study, formalize, and generalize the pure spinor superfield formalism from a rather nontraditional perspective. To set the stage, we review the notion of a multipl…
Maximally twisted eleven-dimensional supergravity
Richard Eager, Fabian Hahner
We perform the maximal twist of eleven-dimensional supergravity. This twist is partially topological and exists on manifolds of holonomy. Our derivation starts w…
