Stability of relativistic stars with scalar hairs
Ryotaro Kase, Rampei Kimura, Seiga Sato +1
We study the stability of relativistic stars in scalar-tensor theories with a nonminimal coupling of the form , where depends on a scalar field and is the Ricci…
Stability of Hybrid Higgs Inflation
Seiga Sato, Kei-ichi Maeda
Hybrid Higgs inflation model is a hybrid type of the so-called Higgs inflation model with the conventional non-minimal coupling to a scalar curvature and new Higgs inflatio…
Stable Singularity-free Cosmological Solutions in non-projectable Horava-Lifshitz Gravity
Mitsuhiro Fukushima, Yosuke Misonoh, Shoichiro Miyashita +1
We find stable singularity-free cosmological solutions in non-flat Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime in the context of Hořava-Lifshitz (HL) theory. Although we e…
Hybrid Higgs Inflation: The Use of Disformal Transformation
Seiga Sato, Kei-ichi Maeda
We propose a hybrid type of the conventional Higgs inflation and new Higgs inflation models. We perform a disformal transformation into the Einstein frame and analyze the backgroun…
