Generalising gravitationally induced decoherence beyond linear environmental interactions in a microscopic quantum mechanical toy model
Max Joseph Fahn, Renata Ferrero, Kristina Giesel +1
We generalise the quantum mechanical toy model for gravitationally induced decoherence presented in Xu, Blencowe (2022) and Domi et al. (2024). In contrast to earlier formulations,…
On the nature of entangling photons in horizon-induced decoherence
Max Joseph Fahn, Alessandro Pesci
Recently, it was discussed how the presence of a Killing horizon induces decoherence on a quantum system in a superposition of states. Focusing on the case of an electrically-charg…
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…
Understanding gravitationally induced decoherence parameters in neutrino oscillations using a microscopic quantum mechanical model
Alba Domi, Thomas Eberl, Max Joseph Fahn +5
In this work, a microscopic quantum mechanical model for gravitationally induced decoherence introduced by Blencowe and Xu is investigated in the context of neutrino oscillations.…
A gravitationally induced decoherence model using Ashtekar variables
Max Joseph Fahn, Kristina Giesel, Michael Kobler
We consider the coupling of a scalar field to linearised gravity and derive a relativistic gravitationally induced decoherence model using Ashtekar variables. The model is formulat…
Dynamical Properties of the Mukhanov-Sasaki Hamiltonian in the context of adiabatic vacua and the Lewis-Riesenfeld invariant
Max Joseph Fahn, Kristina Giesel, Michael Kobler
We use the method of the Lewis-Riesenfeld invariant to analyze the dynamical properties of the Mukhanov-Sasaki Hamiltonian and, following this approach, investigate whether we can…
