Ringing of rapidly rotating black holes in effective field theory
Tom van der Steen, Simon Maenaut, Stef J. B. Husken +5
Within the effective field theory approach to gravity, deviations from general relativity can be systematically described by higher-curvature operators. However, computing the resu…

Quadratic gravity corrections to scalar QNMs of rapidly rotating black holes
Stef J. B. Husken, Tom van der Steen, Simon Maenaut +6
In an effective-field-theory framework for gravity, black-hole quasinormal mode spectra acquire corrections in quadratic-curvature, scalar-tensor extensions of general relativity.…

Holographic (Eternal) Inflation
Thomas Hertog, Jef Pauwels, Victoria Venken
We identify a minisuperspace of complex deformations of ABJM theory for which the partition function specifies the amplitude of an eternally inflating universe. The boundary theory…
