Real-space entanglement in the Cosmic Microwave Background
Jerome Martin, Vincent Vennin
We compute the entanglement entropy, mutual information and quantum discord of the Cosmic Microwave Background (CMB) fluctuations in real space. To that end, we first show that mea…
On the choice of the collapse operator in cosmological Continuous Spontaneous Localisation (CSL) theories
Jerome Martin, Vincent Vennin
The Continuous Spontaneous Localisation (CSL) theory in the cosmological context is subject to uncertainties related to the choice of the collapse operator. In this paper, we const…
A response to criticisms on "CMB Constraints Cast a Shadow on CSL Model"
Jerome Martin, Vincent Vennin
Our recent letter "Cosmic Microwave Background Constraints Cast a Shadow On Continuous Spontaneous Localization Models" [arXiv:1906.04405] has recently been criticised in [G. R. Be…
Reply to "Bouncing Universes and their perturbations: remarks on a toy model"
Jerome Martin, Patrick Peter
In this web note, we reply to a recent paper, gr-qc/0404126, confirming a previous work of ours in which a cosmological bouncing phase was shown to have the ability of modifying th…
Geodesic Deviation in Kaluza-Klein Theories
Richard Kerner, Jerome Martin, Salvatore Mignemi +1
We study in detail the equations of the geodesic deviation in multidimensional theories of Kaluza-Klein type. We show that their 4-dimensional space-time projections are identical…
Green Functions for Topology Change
Jerome Martin, Nelson Pinto-Neto, Ivano Damiao Soares
We explicitly calculate the Green functions describing quantum changes of topology in Friedman-Lemaitre-Robertson-Walker Universes whose spacelike sections are compact but endowed…
