Higher Lovelock Curvature Terms Favor Local Nakedness in Dust Collapse
Apratim Ganguly, Radouane Gannouji, Akshay Kumar
We show that higher-curvature Lovelock terms do not restore local cosmic censorship in spherical dust collapse, but instead promote the local visibility of central shell-focusing s…
Neutron stars in Poincaré gauge gravity with quadratic torsion
Chaitanya Vashistha, Radouane Gannouji, Apratim Ganguly
We study static neutron stars in an algebraic sector of Poincaré gauge gravity with parity-even and parity-odd quadratic torsion invariants. Since torsion is non-propagating, the c…
Oppenheimer-Snyder Collapse in f(R) Gravity : Stalemate or Resolution?
Soumya Chakrabarti, Apratim Ganguly, Radouane Gannouji +1
We study the Oppenheimer--Snyder (OS) collapse problem in metric gravity by matching a homogeneous dust Friedmann--Lemaître--Robertson--Walker (FLRW) interior to a generaliz…
Entanglement inequalities, black holes and the architecture of typical states
Radouane Gannouji, Ayan Mukhopadhyay, Nicolas Pinochet
Using the holographic realization of the Araki--Lieb (AL) inequality, we argue that the leading entanglement plateau constrains the organization of typical pure states in a fixed-$…
Nonlinear dynamics in Horndeski gravity: a renormalized approach to effective gravitational coupling
Luca Amendola, Carla Bernal, Radouane Gannouji
This paper develops a renormalized perturbation theory framework for nonlinear structure formation in a broad class of modified gravity models that exhibit Vainshtein screening, wi…
Characteristic initial value problems for the Einstein-Maxwell-scalar field equations in spherical symmetry
Thomas Mädler, Radouane Gannouji, Emanuel Gallo
The characteristic initial boundary problem is discussed in spherical symmetry for the Einstein-Maxwell-scalar field equations. It is formulated for an affine-null metric and the r…
