A rotating GUP black hole: metric, shadow, and bounds on quantum parameters
Federica Fragomeno, Samantha Hergott, Saeed Rastgoo +1
Recently, for the first time, a metric of a static spherically symmetric generalized uncertainty inspired quantum black hole was derived. We apply the modified Newman-Janis algorit…
Implementing Hamiltonian Renormalization Group Flow on Quantum Computers with VAPOR
Federica Fragomeno, Jorden Roberts, Saeed Rastgoo +1
While Hamiltonian Lattice Gauge Theory is gaining traction, today's limited numerical capacity leaves simulations affected by discretization errors. This motivates the implementati…
Relational quantum dynamics of the black hole interior: singularity resolution and quantum bounce
Paolo Fragolino, Saeed Rastgoo
We study the interior of the Schwarzschild black hole which is isometric to the Kantowski-Sachs cosmological model, using a fully relational and gauge-invariant quantization framew…
Effective Improved-GUP Cosmology: Emergent FLRW Universe without a Bounce
Saeed Rastgoo, Wilfredo Yupanqui
We investigate the effective dynamics of a spatially flat FLRW universe coupled to a massless scalar field by applying the improved generalized uncertainty principle (GUP)-inspired…
Spherically Symmetric Gravity on a Graph I: Theoretical Foundations
Klaus Liegener, Saeed Rastgoo, Jorden Roberts
This manuscript is the first in a series of instalments that investigate spherically symmetric solutions within the effective dynamics program of Loop Quantum Gravity. The choice o…
Canonical Electrodynamics in Ashtekar-Barbero variables
Federica Fragomeno, Saeed Rastgoo
We present the full Hamiltonian analysis of electrodynamics, including fermions, photons, and their interaction, on a general curved spacetime in Ashtekar-Barbero variables. Only t…
