Constructing an entangled state in Heisenberg picture for inflationary cosmology
Abasalt Rostami, Javad T. Firouzjaee
The effects of the entanglement of the inflaton field which initially entangled with those of another field on observables like power spectrum are known in the context of the Schrö…
Quantum decoherence from entanglement during inflation
Abasalt Rostami, Javad T. Firouzjaee
We study the primary entanglement effect on the decoherence of fields reduced density matrix which are in interaction with another fields or independent mode functions. We show tha…
Charged cosmological black hole
Rahim Moradi, Clément Stahl, Javad T. Firouzjaee +1
The cosmological black holes are black holes living not in an asymptotically flat universe but in an expanding spacetime. They have a rich dynamics in particular for their mass and…
Long gradient mode and large-scale structure observables
Alireza Allahyari, Javad T. Firouzjaee
We extend the study of long mode perturbations to other large scale observables such as cosmic rulers, galaxy number counts and halo bias. The long mode is a pure gradient mode tha…
