Analysis of observables in FLRW spacetime
P. Fernandez de Cordoba, S. Gavasso, J. M. Isidro
We consider a positively curved FLRW spacetime as a background in which a nonrelativistic quantum particle propagates according to the Schroedinger equation. The probability fluid…

On the cosmological constant as a quantum operator
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We regard the cosmological fluid within an exponentially expanding FLRW spacetime as the probability fluid of a nonrelativistic Schroedinger field. The scalar Schroedinger particle…

On the cosmological constant of flat FLRW spacetime
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We consider an exponentially expanding, flat, Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe filled with a free Schroedinger field. The probability fluid of the latter is used…
