A gravitationally induced decoherence model for photons in the context of the relational formalism
Max Joseph Fahn, Kristina Giesel, Roman Kemper
We formulate a model of gravitationally induced decoherence for photons starting from Maxwell theory coupled to linearised gravity, expressed in terms of Ashtekar-Barbero variables…
Horizon quantum geometries and decoherence
Max Joseph Fahn, Alessandro Pesci
There is mounting theoretical evidence that black hole horizons induce decoherence on a quantum system, say a particle, put in a superposition of locations, with the decoherence fu…
Effects of quantum geometry on the decoherence induced by black holes
Max Joseph Fahn, Alessandro Pesci
Recently, it has been shown that a quantum system held in spatial superposition and then eventually recombined does experience decoherence from black hole horizons, at a level incr…
Gravitationally induced decoherence of a scalar field: investigating the one-particle sector and its interplay with renormalisation
Max Joseph Fahn, Kristina Giesel
We investigate the one-particle sector for the field-theoretical model of gravitationally induced decoherence for a scalar field in [1] with a special focus on the renormalisation…
