Hoavo Hova
TL;DR
This paper investigates a quintessence scalar field with an exponential potential, demonstrating that it can drive the universe's current accelerated expansion and potentially sustain it forever.
Contribution
It introduces a specific exponential potential for quintessence and analyzes its implications for cosmic acceleration.
Findings
Universe is currently accelerating
Acceleration could continue indefinitely
Scalar field model explains observed acceleration
Abstract
In this paper we study a quintessence scalar field in a potential exponentially decreasing with e-folding number, and show that the universe is currently undergoing an accelerated expansion and could probably remain accelerating indefinitely.
