Dressing a naked singularity with zero-point length
Kimet Jusufi, Francisco S. N. Lobo
We regularize the central density cusp of the Joshi--Malafarina--Narayan spacetime using a normalized kernel motivated by a zero-point length. For an unbounded cusp, the convolutio…
Planck-scale black hole remnants inside neutron stars
Kimet Jusufi, Francisco S. N. Lobo
We examine a Planck-scale regular black-hole remnant in neutron-star matter using a T-duality-inspired effective geometry and explicitly separate geometrical results from assumptio…
Quantum-gravity-inspired Alcubierre warp-drive geometries
Kimet Jusufi, Francisco S. N. Lobo
String T-duality, through its correspondence with path-integral duality, endows the low-energy propagator with a zero-point length that softens the short-distance…
Reconstructing gravity from generalized entropies: exact Lagrangians
Ankit Anand, Sahil Devdutt, Kimet Jusufi +2
Generalized horizon entropies are widely used as theoretical modifications of the Bekenstein-Hawking area law, but through the Wald construction they may also encode modifications…
From arithmetic spectra to a quantum-corrected black hole geometry
Kimet Jusufi, Ankit Anand
The Euler product of the Riemann zeta function is the partition function of a free bosonic gas whose mode energies are the logarithms of the primes. We show that this arithmetic ga…
Entanglement islands and information recovery from near-extremal regular black holes
Ankit Anand, Kimet Jusufi, Amir A. Khodahami +1
We investigate the Page curve and information recovery in a near-extremal regular black hole inspired by T-duality, in which the central singularity is resolved by a minimal length…
Entropy-geometry correspondence as effective nonlocal gravity
Kimet Jusufi, Ankit Anand
We develop an operator formulation of the entropy-geometry correspondence for static, spherically symmetric gravity. Starting from a generalized entropy, we reconstruct an effectiv…
A regularized photon-pair geometry motivated by the ER=EPR conjecture
Kimet Jusufi, Francisco S. N. Lobo, Douglas Singleton
We regularize the Aichelburg-Sexl shock-wave geometry for massless particles by smearing the point-like source over a string-inspired length scale . A radial extension of the…
Unified dark sector and Hubble-tension alleviation in scalar-vector-tensor gravity
Kimet Jusufi, Amir A. Khodahami, Ahmad Sheykhi +2
We investigate a scalar-vector-tensor theory in which matter is minimally coupled to a Jordan-frame metric , while a massive vector sector interacts with…
Zero-point length as a topological protection of black hole regularity
Ankit Anand, Kimet Jusufi, Cosimo Bambi
We investigate the thermodynamic topology of regular black holes with zero-point length using an extended first law that includes the zero-point length stored in the geometry. By t…
