Autor: David Viennot

We present a toy model of a fuzzy Schwarzschild space slice (as a noncommutative manifold), in which quantum mean values and quantum quasi-coherent states (states minimizing the quantum uncertainties) have properties close to the classical slice of (

Publikováno v: Gen.Rel.Grav.
Gen.Rel.Grav., 2021, 53 (4), pp.39. ⟨10.1007/s10714-021-02811-5⟩

International audience; In this paper, an open quantum system theory for spinfoams is developed. This new formalism aims at deriving an effective Lindblad equation to compute the reduced dynamics of a quantum gravitational field. The system parameter

In study of muon neutrino disappearance at 810 km, the NOvA experiment finds flavor mixing of the atmospheric sector to deviate from maximal ($\sin^2\theta_{23} = 0.5$) by 2.6 $\sigma$. The result is in tension with the 295-km baseline measurements o
