Entropy Obstruction to Closed Semiclassical Bounces
Naman Kumar
We prove a finite- singularity theorem for semiclassical spacetimes with compact Cauchy slices. Let a compact Cauchy slice be divided by a compact surface into regions $B…
Reverse Isoperimetry from Boundary--Completed Canonical Energy
Naman Kumar
The reverse isoperimetric conjecture states that, at fixed thermodynamic volume, Schwarzschild--AdS black holes maximize entropy. We show that its local fixed-volume form admits a…
Quantum Black Hole Chemistry from Double Holography
Naman Kumar
Extended black hole thermodynamics highlights a sharp tension in the usual holographic dictionary: at fixed boundary conformal frame, changing the AdS radius changes both the centr…
An Algebraic Resolution of the Firewall Paradox
Naman Kumar
The AMPS firewall argument relies on treating early radiation, late outgoing Hawking modes, and interior partner modes as approximately independent quantum subsystems. In diffeomor…
Massless Islands in Wedge Holography
Naman Kumar
Entanglement islands are most easily realized in doubly holographic models with massive gravitons or non-gravitating baths. In wedge holography, however, Neumann boundary condition…
Topology sums, sectorwise holography, and horizon normalcy
Naman Kumar
The ``holography of information'' (HoI) principle argues that gravity can encode information redundantly in asymptotic observables. Although HoI is ultimately a nonperturbative cla…
A Quantum Weak Cosmic Censorship and Its Proof
Naman Kumar
Recent work has highlighted the deep connection between quantum information and spacetime geometry. Bousso and Shahbazi-Moghaddam (Phys. Rev. Lett. 128, 231301 (2022)) proved that…
Entropy bound and the non-universality of entanglement islands
Naman Kumar
The island prescription reproduces the Page curve and avoids the Almheiri--Marolf--Polchinski--Sully (AMPS) monogamy conflict for suitable radiation subsystems by placing the corre…
Dynamical tidal response of regular black holes: Perturbative analysis and shell EFT interpretation
Arpan Bhattacharyya, Naman Kumar, Shailesh Kumar
We compute the frequency-dependent quadrupolar tidal response of Bardeen, Hayward, and Fan-Wang regular black holes in the polar and axial sectors by solving the coupled gravitatio…
Relativistic Correction to Black Hole Entropy
Naman Kumar
In this paper, we study the relativistic correction to Bekenstein-Hawking entropy in the canonical ensemble and isothermal-isobaric ensemble and apply it to the cases of non-rotati…
Recovering semiclassical Einstein's equation using generalized entropy
Naman Kumar
In this letter, we show that the Semiclassical Einstein's Field Equation can be recovered using the generalized entropy . This approach is reminiscent of non-equilibrium t…
