Non-linear evolution of five-dimensional black strings in effective field theory
Pau Figueras, Ãron D. Kovács, Shunhui Yao
We use numerical relativity to study the non-linear instability of five-dimensional black strings in Einstein-Gauss-Bonnet gravity. Black strings evolve into a series of black hole…

Stable non-linear evolution in regularised higher derivative effective field theories
Pau Figueras, Ãron D. Kovács, Shunhui Yao
We study properties of a recently proposed regularisation scheme to formulate the initial value problem for general (relativistic) effective field theories (EFTs) with arbitrary hi…
