Title: Gravitational decoherence: a non relativistic spin 1/2 fermionic model
Authors: Lorenzo Asprea and Giulio Gasbarri
Abstract summary: We derive a non relativistic model for the gravitational decoherence of spin 1/2 particles. We discuss the differences with the scalar bosonic model and we describe the regimes in which they become negligible.

Abstract: In a previous work [arXiv1905.01121] we have derived a quantum master equation for the dynamics of a scalar bosonic particle interacting with a weak, stochastic and classical gravitational field. As standard matter is made of fermions, such an equation should be suitably extended to describe more relevant experimental situations. Here we derive a non relativistic model for the gravitational decoherence of spin 1/2 particles. We enrich the treatment by considering also a coupling with an external classical electromagnetic field. We comment on the differences with the scalar bosonic model and we describe the regimes in which they become negligible.

Integral quantization based on the Heisenberg-Weyl group [39.58317527488534]
We develop a framework of integral quantization applied to the motion of spinless particles in the four-dimensional Minkowski spacetime. The proposed scheme is based on coherent states generated by the action of the Heisenberg-Weyl group. A direct application of our model, including a computation of transition amplitudes between states characterized by fixed positions and momenta, is postponed to a forthcoming article.

Ultracold Neutrons in the Low Curvature Limit: Remarks on the post-Newtonian effects [49.1574468325115]
We apply a perturbative scheme to derive the non-relativistic Schr"odinger equation in curved spacetime. We calculate the next-to-leading order corrections to the neutron's energy spectrum. While the current precision for observations of ultracold neutrons may not yet enable to probe them, they could still be relevant in the future or in alternative circumstances.

Correspondence Between the Energy Equipartition Theorem in Classical Mechanics and its Phase-Space Formulation in Quantum Mechanics [62.997667081978825]
In quantum mechanics, the energy per degree of freedom is not equally distributed. We show that in the high-temperature regime, the classical result is recovered.

Path integral in position-deformed Heisenberg algebra with strong quantum gravitational measurement [0.0]
We show that quantum gravity bends the paths of particles, allowing them to travel quickly from one point to another. It is numerically observed by the decrease in values of classical actions as one increases the quantum gravitational effects.

We study the phenomenon of quantum interference in the presence of external gravitational fields. In the non-relativistic regime, it is possible to come across a gravitational counterpart of the Bohm-Aharonov effect. On the other hand, beyond the Newtonian approximation, the relativistic nature of gravity plays a crucial role.
