Scalar fields from nonlinear sigma models on black hole spacetimes
Ludovico Machet, Llibert Aresté Saló
Scalar fields with non-trivial kinetic term derived from a nonlinear sigma model are motivated by UV completions of gravity such as string theory. We discuss the $\mathrm{SL}(2,\ma…
Challenges in the nonlinear evolution of unequal mass binaries in sGB gravity
Llibert Aresté Saló, Daniela D. Doneva, Katy Clough +2
It has only recently become possible to simulate the full nonlinear dynamics of binary black holes in scalar-Gauss-Bonnet theories of gravity. The simulations remain technically ch…
Solving the initial conditions problem for modified gravity theories
Sam E. Brady, Llibert Aresté Saló, Katy Clough +2
Modified gravity theories such as Einstein scalar Gauss Bonnet (EsGB) contain higher derivative terms in the spacetime curvature in their action, which results in modifications to…
Puncture gauge formulation for Einstein-Gauss-Bonnet gravity and four-derivative scalar-tensor theories in spacetime dimensions
Llibert Aresté Saló, Katy Clough, Pau Figueras
We develop a modified CCZ4 formulation of the Einstein equations in spacetime dimensions for general relativity plus a Gauss-Bonnet term, as well as for the most general pari…
