A note on some physical and cosmological implications of conformal metric fluctuations

Decoherence of quantum wave packets due to interaction with conformal space–time fluctuations

“…With this in mind we consider the possible sources of incoherent waves in the conformal gravitational field and examine whether these are likely to be sufficient to produce an experimentally observable effect. One possibility that we consider is that there may be cosmological sources of these waves, but an analysis, based on arguments originally proposed by Rosales and Sánchez-Gómez (1995), suggests that these are unlikely to be observable. Another possible source of conformal gravitational waves are the quantum zero-point energy fluctuations in the conformal field.…”

Microscopic foundation of thermodynamics, transition to classicality and regularization of gravitational-collapse singularities within Non-unitary $4$-th Derivative Gravity classically equivalent to Einstein gravity and its Newtonian limit

“…These considerations, supported by the mentioned suggestions derived from a phenomenological analysis [34] about the possible role of negative energy fields, may provide substantial clues for the possible extensions of the model towards a relativistic theory of gravity-induced localization. On the other hand a Yukawa interaction with a (positive energy) scalar field emerges also moving from Einstein's theory of gravitation, if one confines consideration to conformal space-time fluctuations in a linear approximation [64,65].…”
