Gravitational Enstrophy: Local Geometric Origin and Energy-Cascade Constraints
Luis Lehner
Two-dimensional incompressible fluids conserve energy and enstrophy in the inviscid limit. Fjørtoft's argument uses this pair to constrain nonlinear energy transfer. We examine the…
Matching Tidal Deformability (Wilson) Coefficients to Black Hole Love Numbers in Higher-Curvature Gravity
Luohan Wang, Luis Lehner, Maitá Micol +1
We present a consistent mapping between tidal deformability coefficients (tidal Love numbers) and Wilson coefficients in effective field theory (EFT) descriptions of higher-curvatu…
Modified Teukolsky formalism: Null testing and numerical benchmarking
Fawzi Aly, Mahmoud A. Mansour, Luis Lehner +3
Next-generation gravitational-wave detectors will make black-hole ringdown an increasingly sensitive probe of small departures from General Relativity in the strong-field regime. T…
A bulk model for dissipation and fixing EFT equations on its boundary
A. Besharat, L. Lehner, J. Radkovski
Effective field theories (EFTs) with higher derivatives often yield equations of motion that define ill-posed problems. We present an action-based approach that supplements a recen…
Sourced Carrollian Fluids Dual to Black Hole Horizons
Sercan Hüsnügil, Luis Lehner
The (degenerate) geometry of event horizons is linked to Carrollian fluids. We investigate the behavior of event horizons via a perturbative coupling to a massless scalar field, ma…
Emergent Turbulence in Nonlinear Gravity
Sizheng Ma, Luis Lehner, Huan Yang +3
Gravity in nonlinear and dynamical regimes underpins spectacular astrophysical phenomena and observable consequences, from the early universe to black hole collisions. In these ext…
