Gravitational decoherence (GD) refers to the effects of gravity in actuating the classical
appearance of a quantum system. Because the underlying processes involve issues in …

Black holes, initially thought of as very interesting mathematical and geometric solutions of
general relativity, over time, have come up with surprises and challenges for modern …

Concepts related to probability permeate physics. This is most obvious in statistical
mechanics, in which probabilities appear explicitly, but even in cases when predictions are …

We introduce configuration space path integrals for quantum fields interacting with classical
fields. We show that this can be done consistently by proving that the dynamics are …

In order to reconcile the wave-function collapse in quantum mechanics with the finiteness of
signals' propagation in general relativity, we delve into a stochastic version of the Ricci flow …

Consistent dynamics which couples classical and quantum degrees of freedom exists. This
dynamics is linear in the hybrid state, completely positive and trace preserving. Starting from …

Bell's Theorem is the collective name for a family of results, all of which involve the
derivation, from a condition on probability distributions inspired by considerations of local …

In this work we consider a wide variety of alternatives opened when applying the continuous
spontaneous localization (CSL) dynamical collapse theory to the inflationary era. The …

The eternal inflation problem continues to be considered one of standard's cosmology most
serious shortcomings. This arises when one considers the effects of" quantum fluctuations" …

Recent works have proved that semiclassical theories of gravity needed not be
fundamentally inconsistent, at least in the Newtonian regime. Using the machinery of …
