TL;DR
This paper proposes a mechanism linking the observable cosmological constant to its natural value through quantum state installation in the early Universe, with implications for inflation constraints.
Contribution
It introduces a novel dynamical relation between the cosmological constant and quantum state installation during inflation.
Findings
The probability of zero quanta states is exponentially suppressed.
Quantum fluctuations constrain the total amount of inflation.
A new perspective on the cosmological constant's observed value.
Abstract
An artificial scale of observable cosmological constant is dynamically related to its natural bare value due to an installation of relevant coherent state for the inflationary field in a finite volume of early Universe, because of exponential suppression of probability to find the state with zero number of quanta. Homogeneous quantum fluctuations of the field actually put hard constraints on the total amount of inflation.
