Hanbury-Brown Twiss effect, squeezed gravitons and the photon correlations
Massimo Giovannini
Unlike the gravitational waves classically generated by moving macroscopic masses, the diffuse backgrounds of gravitons originate most likely from zero-point fluctuations of the gr…
The initial states of high frequency gravitons
Massimo Giovannini
After distinguishing the role of classical and quantum inhomogeneities in cosmological backgrounds, we constrain the initial states of the relic gravitons as soon as the different…
Invisible gravitons and large-scale magnetism
Massimo Giovannini
The large-scale limits on the relic signals of gravitational radiation complement the bounds coming from the interferometric detectors (in the audio band) and from the pulsar timin…
The multiplicity distributions of the high frequency gravitons
Massimo Giovannini
When the gravitons are created thanks to the variation of the space-time curvature the multiplicity distributions quantify the probability of producing a given number of species ar…
Entropy bounds from quantum thermodynamics
Massimo Giovannini
Within an inherently classical perspective, there is always an unavoidable energy cost associated with the information deletion and this common lore is at the heart of the Landauer…
Ultra-high frequency spikes of relic gravitons
Massimo Giovannini
The maximal frequency domain of the cosmic gravitons falls in the THz region where, without conflicting with the existing phenomenological bounds, only few particles with opposite…
