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…
From Størmer to Schwarzschild: Analytical Dynamics of Charged Particles in a Dipole Magnetosphere
Francisco S. N. Lobo, Tiberiu Harko
We investigate the conservative dynamics of relativistic charged particles in a Schwarzschild spacetime threaded by an externally supported dipolar magnetic field. The gravitationa…
Radiation reaction in the classical relativistic Størmer problem
Francisco S. N. Lobo, Tiberiu Harko
We extend the classical relativistic Størmer problem by incorporating radiation reaction through the Landau--Lifshitz formulation, thereby providing a self-consistent description o…
Exact solutions, trajectories and radiation patterns in the classical relativistic Störmer problem
Tiberiu Harko, Francisco S. N. Lobo
We investigate the relativistic generalization of the classical Störmer problem, which describes the motion of charged particles in a purely magnetic dipole field. By incorporating…
Helicity-supported stationary spacetimes: A class of finite-energy, horizonless, axisymmetric solutions
Francisco S. N. Lobo, Tiberiu Harko
We construct a class of stationary, axisymmetric, horizonless spacetimes whose curvature is generated entirely by smooth, localised differential rotation , while the spatial…
On the possibility of emergent light cones from relational shape dynamics
Francisco S. N. Lobo
We show that a universal propagation scale can emerge from purely relational, scale-invariant -body dynamics formulated on shape space, i.e. the space of configurations modulo t…
Emergence of ER=EPR from non-local gravitational energy
Kimet Jusufi, Francisco S. N. Lobo, Emmanuel N. Saridakis +1
We construct a class of wormhole geometries supported by the non-local gravitational self-energy that regularizes the particle and black-hole sectors of spacetime. Using this frame…
Spontaneous wave function collapse from non-local gravitational self-energy
Kimet Jusufi, Douglas Singleton, Francisco S. N. Lobo
We incorporate non-local gravitational self-energy, motivated by string-inspired T-duality, into the Schrödinger-Newton equation. In this framework spacetime has an intrinsic non-l…
