A Class of Exact Single-Field Inflationary Solutions beyond Slow Roll
Jia-Wei Zhang, Bai-Cian Ke, Yao Yu +2
We construct exact solutions for single-field inflaton dynamics without invoking the slow-roll approximation. A suitable change of variables reduces the background equation to an A…

Power-Law Inflation Survives Observational Constraints
Yao Yu, Wen-Zhang Feng, Hong-Song Xie +2
Power-law inflation has stood as a classical model in inflationary cosmology since the early 1980s, prized for its exact analytical solutions and ability to naturally resolve the B…
