Classical Universe Arising from Quantum Cosmology
S. Jalalzadeh, M. Rashki, S. Abarghouei Nejad
In this paper, we study the classical limit and unitary evolution of quantum cosmology by applying the Weyl--Wigner--Groenewold--Moyal formalism of deformation quantization to quan…

The Quantum State Of The Universe From Deformation Quantization and Classical-Quantum Correlation
M. Rashki, S. Jalalzadeh
In this paper we study the quantum cosmology of homogeneous and isotropic cosmology, via the Weyl-Wigner-Groenewold-Moyal formalism of phase space quantization, with perfect fluid…

Holography from quantum cosmology
M. Rashki, S. Jalalzadeh
The Weyl-Wigner-Groenewold-Moyal formalism of deformation quantization is applied to the closed Friedmann-Lemaître-Robertson-Walker (FLRW) cosmological model. We show that the phas…
