Quantum Field Theory Of Cosmological Perturbations Induced By Ultralight Dark Matter
Tomislav Prokopec, Marco Vecchioni
The paper formulates a quantum field‑theoretic description of ultralight scalar dark matter and studies its effect on linear cosmological perturbations and graviton dynamics during…
Inflaton perturbations through an Ultra-Slow Roll transition and Hamilton-Jacobi attractors
Tomislav Prokopec, Gerasimos Rigopoulos
We examine the behaviour of the gauge invariant scalar field perturbations in an analytic inflationary model that transitions from slow-roll to an ultra-slow-roll (USR) phase. We f…
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…
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…
Gravitational Noether-Ward identities for scalar field
Tomislav Prokopec
We consider the gravitational Noether-Ward identities for the evolution of general metric perturbations on quantum matter backgrounds. In this work we consider Einstein's gravity c…
Dawn and Twilight Time in Quantum Tunneling
Tinglong Feng, Jesse Moes, Tomislav Prokopec
Metastable decay exhibits a familiar exponential regime bracketed by early-time deviations and late-time power-law tails. We adopt the real-time, flux-based definition of the decay…
