Trans-Planckian Effect in Cosmology
S. Cheraghchi, F. Shojai, M. H. Abbassi
Apart from the assumption that the inflation started at an infinite time in the past, the more realistic initial state of the quantum fluctuations is described by a mixed quantum s…
Birkhoff Theorem for Berwald Finsler spacetimes
Nicoleta Voicu, Christian Pfeifer, Samira Cheraghchi
Finsler spacetime geometry is a canonical extension of Riemannian spacetime geometry. It is based on a general length measure for curves (which does not necessarily arise from a sp…
Running vacuum in QFT in FLRW spacetime: The dynamics of from the quantized matter fields
Cristian Moreno-Pulido, Joan Sola Peracaula, Samira Cheraghchi
Phenomenological work in the last few years has provided significant support to the idea that the vacuum energy density (VED) is a running quantity with the cosmological evolution…
