Description
We investigate how accelerated frames influence the cosmic evolution of a semi-classical universe
and propose that these effects can lead to thermalization at the quantum cosmological level. Our
primary research question is whether transformations in super-space, the configuration space of
the gravitational field can yield a mixed (and thus thermal) density matrix for the universe.
To address this, we apply a specific change of coordinates in super-space and analyze the WKB
wavefunction, revealing that it undergoes a Bogoliubov transformation. This transformation, in
turn, generates a mixed density matrix, signifying the emergence of thermal behavior.
Notably, our approach clarifies that this thermalization does not mirror the standard concept of
particle creation in uniformly accelerated (Rindler) observers; rather, it reflects a subtler
phenomenon linked to the geometry of super-space itself. We further demonstrate that the superspace transformation can be viewed as a double Rindler transformation of real space-time
coordinates, highlighting the deep geometric parallels between cosmological and accelerated
frames. These results suggest that acceleration-driven thermalization may play an important role
in semi-classical cosmology, offering new insights into how quantum and geometric effects
intertwine to shape the early universe.
