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…

Gauge invariant cosmological perturbations for the nonminimally coupled inflaton field
Jan Weenink, Tomislav Prokopec
We construct the gauge invariant free action for cosmological perturbations for the nonminimally coupled inflaton field in the Jordan frame. For this the phase space formalism is u…
