Examples
-
The simplest models assume that the slope - also called the inflaton potential - resembles a very shallow parabola.
-
Inflation was triggered by a field in the early universe called the inflaton, whose energy density fell slowly, like a ball rolling down a gentle slope.

-
If the idea is correct, inflation was triggered by an energy field called the inflaton that drove the early universe to rapidly expand, stretching out and freezing what otherwise would have been random, short-lived quantum fluctuations.

This paradigm relies upon a repulsive "inflaton" causing accelerated expansion.

-
As scientists once invoked epicycles to explain planetary motions, a repulsive "inflaton" was hypothesised to explain CMB uniformity.
-
In many of such theories, the scalar field equals the inflaton field, which is needed to explain the inflation of the universe after the Big Bang, as the dominating factor of the quintessence or Dark Energy.
-
The scalar field, or inflaton, cascaded down its field potential and induced this configuration.
-
These anisotropies are largely due to a quantum fluctuation, such as the scalar field of inflation inflaton, and we would not expect statistics which violated this, such as significant non-Gaussian distributions.
