NANOGrav Signal from the End of Inflation and the LIGO Mass and Heavier Primordial Black Holes
Amjad Ashoorioon, Kazem Rezazadeh, Abasalt Rostami
Releasing the 12.5-year pulsar timing array data, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported the evidence for a stochastic co…
Examining the end of inflation with primordial black holes mass distribution and gravitational waves
Amjad Ashoorioon, Abasalt Rostami, Javad T. Firouzjaee
We explicitly construct a double-field inflationary model, which satisfies the latest Planck constraints at the cosmic microwave background (CMB) scales and produces the whole dark…
EFT Compatible PBHs: Effective Spawning of the Seeds for Primordial Black Holes during Inflation
Amjad Ashoorioon, Abasalt Rostami, Javad T. Firouzjaee
Most of the inflationary scenarios that try to explain the origin of Primordial Black Holes (PBHs) from the enhancements of the power spectrum to values of order one, at the releva…
Ramsey Interferometers as a test for the correction to quantum mechanics
Abasalt Rostami, Javad T. Firouzjaee, Mehdi Golshani
By applying the basic concept of the density matrix in an open quantum system and modification of quantum mechanics, we derive Kossakowski-Lindblad equation and different propertie…
Revisiting nonrelativistic limits of field theory: Antiparticles
Javad T. Firouzjaee, Abasalt Rostami, Mahmud Bahmanabadi
Different subtleties and problems associated with a nonrelativistic limit of the field theory to the Schroedinger theory are discussed. In this paper, we revisit different cases of…
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…
Schrödinger field theory in curved spacetime: In-In formalism and three-point function for inflationary background
Abasalt Rostami, Javad T. Firouzjaee
We review the Schrödinger picture of field theory in curved spacetime and using this formalism, the power spectrum of massive non-interacting, minimally coupled scalars in a fixed…
