Discrete symmetries determining scalar quantum modes on the de Sitter spacetime
Ion I. Cotaescu, Gabriel Pascu
The action of the discrete symmetries on the scalar mode functions of the de Sitter spacetime is studied. The invariance with respect to a combination of discrete symmetries is put…

On the rest and flat limits of the scalar modes on the de Sitter spacetime
Ion I. Cotaescu, Gabriel Pascu, Flavius Alin Dregoesc
The scalar mode functions on the spatially flat FLRW chart of the de Sitter spacetime are redefined in order to obtain a natural frequencies separation in the special local charts…

How to kill the Unruh effect
Ion I. Cotaescu
How to kill the Unruh effect? Very simple, by requiring the Rindler transformation to behave continuously for vanishing acceleration. Then the Unruh effect disappears as we show in…
