Generalized early dark energy and its cosmological consequences
Tatsuki Kodama, Takumi Shinohara, Tomo Takahashi
We investigate cosmological consequences of a generalized early dark energy (EDE) model where a scalar field behaves as dark energy at various cosmological epochs for a broad range…

Nonminimally Assisted Inflation: A General Analysis
Sang Chul Hyun, Jinsu Kim, Tatsuki Kodama +2
The effects of a scalar field, known as the "assistant field," which nonminimally couples to gravity, on single-field inflationary models are studied. The analysis provides analyti…

Relaxing inflation models with non-minimal coupling: A general study
Tatsuki Kodama, Tomo Takahashi
We investigate the predictions of inflation models with a non-minimal coupling to gravity for inflationary observables such as the spectral index and tensor-to-scalar ratio in a ge…
