Backreaction of a massless minimally coupled scalar field from inflationary quantum fluctuations
Drazen Glavan, Tomislav Prokopec, Vasileios Prymidis
In this paper we study a massless, minimally coupled scalar field in a FLRW spacetime with periods of different constant deceleration parameter. We assume the Bunch-Davies vacuum d…
Electrodynamic Effects of Inflationary Gravitons
D. Glavan, S. P. Miao, T. Prokopec +1
We calculate the one-loop corrections from inflationary gravitons to the electromagnetic fields of a point charge and a point magnetic dipole on a locally de Sitter space backgroun…
Frame independent cosmological perturbations
Tomislav Prokopec, Jan Weenink
We compute the third order gauge invariant action for scalar-graviton interactions in the Jordan frame. We demonstrate that the gauge invariant action for scalar and tensor perturb…
Symmetry breaking in de Sitter: a stochastic effective theory approach
Gianrocco Lazzari, Tomislav Prokopec
We consider phase transitions on (eternal) de Sitter in an O(N) symmetric scalar field theory. Making use of Starobinsky's stochastic inflation we prove that deep infrared scalar m…
An exact solution of the Dirac equation with CP violation
Tomislav Prokopec, Michael G. Schmidt, Jan Weenink
We consider Yukawa theory in which the fermion mass is induced by a Higgs like scalar. In our model the fermion mass exhibits a temporal dependence, which naturally occurs in the e…
