Exotic gravity theory in topologically non-trivial spacetimes
P. S. Howe, U. Lindström
An exotic linearised theory of superconformal gravity in superspace has been proposed by C.M. Hull. In this note we discuss the bosonic sector of this model in topolog…
(Anti-)De Sitter null strings and Carroll-Weyl symmetry
Ulf Lindström, Bo Sundborg
We construct a null string in a novel way by lifting the standard tensionless string to . Gauging worldsheet scale symmetry introduces terms in the action breaking…
Ricci-flat metrics from gauged linear -models without RG flow
Dmitri Bykov, Ondrej Hulik, Ulf Lindström +2
We investigate a class of Ricci-flat Kähler metrics on generalized conifolds constructed via gauged linear sigma models (GLSMs) with indefinite signature. By introducing shadow coo…
Super Yang-Mills with partially non-linear extended supersymmetry
Fotis Farakos, Ulf Lindström
We discuss 4D N=2 non-abelian gauge theories where one supersymmetry is preserved while the other one is spontaneously broken and non-linearly realized. The goldstino resides in a…
Gravitational currents and charges from conformal Killing-Yano tensors
Chris Hull, Ulf Lindström, Maxwell L. Velásquez Cotini Hutt
We construct a set of higher-form conserved currents on spacetimes admitting conformal Killing-Yano tensors. We find relations between these currents that allow the charge given by…
Exotic gravity theory in loop space
P. S. Howe, U. Lindström
An exotic linearised theory of superconformal gravity in D = 6, (4,0) superspace, proposed by C. Hull, is discussed in loop space with focus on its bosonic sector. Pursuing an anal…
