Highest-weight truncation, graded EFT structure, and renormalization of black hole Love numbers
Naman Kumar
The static tidal Love numbers of four-dimensional black holes vanish identically, unlike their nontrivial dynamical response at finite frequency. Recent work has provided three com…
A proof of the reverse isoperimetric inequality using a geometric-analytic approach
Naman Kumar
We present a proof of the reverse isoperimetric inequality - a central conjecture in extended black hole thermodynamics - for black holes in Einstein gravity with , emplo…
Marginal IR running of Gravity as a Natural Explanation for Dark Matter
Naman Kumar
We propose that the infrared (IR) running of Newton's coupling provides a simple and universal explanation for large-distance modifications of gravity relevant to dark matter pheno…
Extended black hole thermodynamics in a DGP braneworld
Naman Kumar
We develop extended black-hole thermodynamics on a Dvali--Gabadadze--Porrati (DGP) brane by promoting the brane tension to a thermodynamic variable within the extended Iyer--W…
Love beyond Einstein: Metric reconstruction and Love number in quadratic gravity using WEFT
Arpan Bhattacharyya, Saptaswa Ghosh, Naman Kumar +2
We study tidal Love numbers of static black holes in four-dimensional quadratic theory of gravity, extending the result of GR. We use worldline effective field theory (WEFT) method…
On the Accelerated Expansion of the Universe
Naman Kumar
If we look from a quantum perspective, the most natural way in which the universe can be created is in entangled pairs whose time flow is oppositely related. This suggests the idea…
