Generalised Geometry and Consistent Truncations on Branes
Jieming Lin, Kellogg S. Stelle, Daniel Waldram
In this note we show how the consistent truncations on half-supersymmetric branes of Leung and Stelle and Lin, Skrzypek and Stelle fit into the general exceptional generalised geom…
Scalar-induced gravitational waves in spatially covariant gravity
Jiehao Jiang, Jieming Lin, Xian Gao
We investigate scalar-induced gravitational waves (SIGWs) in the framework of spatially covariant gravity (SCG), a broad class of Lorentz-violating modified gravity theories respec…
Interplay of Intersecting Branes and Consistent Embeddings
Jieming Lin, Torben Skrzypek, K. S. Stelle
We explore consistent truncations from 10d/11d supergravity to supergravity theories on brane worldvolumes. Supersymmetric black-brane solutions to these lower-dimensional theories…
Compactification on Calabi-Yau threefolds: Consistent truncation to pure supergravity
Jieming Lin, Torben Skrzypek, K. S. Stelle
We study compactifications of eleven- and ten-dimensional maximal supergravity on Calabi-Yau threefolds. We explicitly construct truncations to pure supergravity with eight superch…
