Due to the interaction of physics and astrophysics we are witnessing in these years a
splendid synthesis of theoretical, experimental and observational results originating from …

Whereas semiclassical gravity is based on the semiclassical Einstein equation with sources
given by the expectation value of the stress-energy tensor of quantum fields, stochastic semi …

Bringing together the key ideas from nonequilibrium statistical mechanics and powerful
methodology from quantum field theory, this 2008 book captures the essence of …

We develop a formalism to calculate the response of a model gravitational wave detector to
a quantized gravitational field. Coupling a detector to a quantum field induces stochastic …

The microscopic quantum field theory origins of warm inflation dynamics are reviewed. The
warm inflation scenario is first described along with its results, predictions and comparison …

According to the inflationary scenario for the very early Universe, all inhomogeneities in the
Universe are of genuine quantum origin. On the other hand, looking at these …

Warm inflation is examined in a multi-field model. Solutions are obtained for expansion e-
folds and scalar density perturbations. Nonequilibrium dynamics is restricted to a regime that …

We study the nonequilibrium evolution of the expectation value of a scalar field in the broken
and unbroken symmetry cases. We find that the particles produced by parametric …

We study quantum noise and decoherence induced by gravitons. We derive a Langevin
equation of geodesic deviation in the presence of gravitons. The amplitude of noise …

We show that when the gravitational field is treated quantum-mechanically, it induces
fluctuations—noise—in the lengths of the arms of gravitational wave detectors. The …
