Unique fermionic vacuum in de Sitter spacetime from hybrid quantum cosmology
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán, Santiago Prado
In this work we show how the criterion of asymptotic Hamiltonian diagonalization originated in hybrid quantum cosmology serves to pick out a unique vacuum for the Dirac field in de…
Fock quantization of the Dirac field in hybrid quantum cosmology: Relation with adiabatic states
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán, Santiago Prado
We study the relation between the Fock representations for a Dirac field given by the adiabatic scheme and the unique family of vacua with a unitarily implementable quantum evoluti…
Asymptotic diagonalization of the fermionic Hamiltonian in hybrid loop quantum cosmology
Beatriz Elizaga Navascués, Guillermo A. Mena Marugán, Santiago Prado
We use the freedom available in hybrid loop quantum cosmology to split the degrees of freedom between the geometry and the matter fields so as to build a quantum field theory for t…
