Constraints on regular black holes with nonminimally coupled electromagnetic fields
Ana Bokulić, Tajron Jurić, Luka Kanai Pejić +2
Construction of physically realistic theories admitting regular black hole solutions remains an important open problem in gravitational physics. While theories with electromagnetic…

Spectral torsion of the internal noncommutative geometry of the Standard Model
Ludwik Dąbrowski, Sugato Mukhopadhyay, Filip Požar
We compute the nonvanishing spectral torsion functional of the internal part of the noncommutative geometry behind the Standard Model. We show that with a suitable modification of…

Noncommutative dyonic black holes sourced by nonlinear electromagnetic fields
Ana Bokulić, Filip Požar
We introduce the first-order noncommutative (NC) corrections to the general nonlinear electrodynamics (NLE) Lagrangian depending on two electromagnetic invariants. The NC deformati…
