Dispersion relation, propagation features and canonical gauge structure of GNLED
Abedennour Dib, José A. Helayël-Neto, Tomislav Prokopec +2
We investigate the propagation properties and canonical gauge structure of Generalised Non-Linear Electrodynamics (GNLED) in the presence of a non-dynamical background field. Start…
Massive scalar's self-mass from gravitons in de Sitter
Dražen Glavan, Shun-Pei Miao, Tomislav Prokopec +1
We compute the fully renormalized one-graviton-loop contribution to the self-mass of a massive scalar field in de Sitter space. The computation is performed using dimensional regul…
Universal Secular External Leg Corrections for Gauge Independent Scalar Self-Mass on de Sitter
D. Glavan, S. P. Miao, T. Prokopec +1
This work concerns a procedure for removing gauge dependence from graviton corrections to the effective field equations for a massless, minimally coupled scalar on de Sitter backgr…
Quantum Field Theory Of Cosmological Perturbations Induced By Ultralight Dark Matter
Tomislav Prokopec, Marco Vecchioni
The growth of primordial perturbations during the matter-dominated era is primarily driven by dark matter. Ultralight scalar fields (ULDM) are a promising candidate for this role,…
Quantum backreaction and stability of topological wormholes
Haris Mehulic, Tomislav Prokopec
We investigate the quantum stability of a timelike topological wormhole with a simple geometry , supported classically by anisotropic fluid. We compute the one-loop…
Cancellation of one-parameter graviton gauge dependence in the effective scalar field equation in de Sitter
Dražen Glavan, Shun-Pei Miao, Tomislav Prokopec +1
We investigate gauge dependence of one-graviton-loop corrections to the effective field equation of the massless, minimally coupled scalar in de Sitter, obtained by including sourc…
