Naturalness in Higgs inflation in a frame independent formalism
Tomislav Prokopec, Jan Weenink
We make use of the frame and gauge independent formalism for scalar and tensor cosmological perturbations developed in Ref. [1] to show that the physical cutoff for 2-to-2 tree lev…
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…
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…
Uniqueness of the gauge invariant action for cosmological perturbations
Tomislav Prokopec, Jan Weenink
In second order perturbation theory different definitions are known of gauge invariant perturbations in single field inflationary models. Consequently the corresponding gauge invar…
The Gaussian entropy of fermionic systems
Tomislav Prokopec, Michael G. Schmidt, Jan Weenink
We consider the entropy and decoherence in fermionic quantum systems. By making a Gaussian Ansatz for the density operator of a collection of fermions we study statistical 2-point…
On decoherence of cosmological perturbations and stochastic inflation
Jan Weenink, Tomislav Prokopec
By making a suitable generalization of the Starobinsky stochastic inflation, we propose a classical phase space formulation of stochastic inflation which may be used for a quantita…
