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…
Testing the conjecture with entangled photons
Kimet Jusufi, Francisco S. N. Lobo, Douglas Singleton
We regularize the Aichelburg-Sexl shock-wave metric for massless particles by smearing the point-like source over a string-inspired length scale , obtaining a singularity-free…
Effective matter sectors from modified entropies
Ankit Anand, Sahil Devdutt, Kimet Jusufi +1
We present a general formalism linking modified entropy functions directly to a modified spacetime metric and, subsequently, to an effective matter sector of entropic origin. In pa…
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…
Regular black holes with gravitational self-energy as dark matter
Kimet Jusufi, Douglas Singleton
We incorporate the effect of non-local gravitational self-energy to obtain a neutral, non-singular spacetime geometry. This is achieved by using a non-local gravitational theory in…
