This article is a brief survey of some approaches to implementing the suggestion that
collapse of the wave function is mediated by gravity. These approaches include: a possible …

Taking the principles of quantum mechanics as they stand and applying them to gravity,
leads to the conclusion that one might be able to generate superpositions of spacetimes, at …

We will describe recent progress of experiments towards realising largemass single particle
experiments to test fundamental physics theories such as quantum mechanics and gravity …

Károlyházy's original proposal, suggesting that space-time fluctuations could be a source of
decoherence in space, faced a significant challenge due to an unexpectedly high emission …

The Schrödinger–Newton system is a nonlinear system obtained by coupling together the
linear Schrödinger equation of quantum mechanics with the Poisson equation of Newtonian …

We propose a stochastic modification of the Schrödinger–Newton equation which takes into
account the effect of extrinsic spacetime fluctuations. We use this equation to demonstrate …

Λ. Applying the DE-UP to both charged and neutral particles, we obtain estimates of two
limiting mass scales, expressed in terms of the fundamental constants {G, c, h, Λ, e} …

We highlight three conflicts between quantum theory and classical general relativity, which
make it implausible that a quantum theory of gravity can be arrived at by quantising classical …

This thesis contributes to the debate on the outstanding issue of quantum gravity, fitting into
the context of the upcoming related experimental era. We part ways with the conventional …
