Gravitational decoherence: a non relativistic spin 1/2 fermionic model
arXiv:2012.01326 · doi:10.1103/PhysRevD.104.024043
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.
