Cosmology in non-minimal Yang-Mills/Maxwell theory
Kazuharu Bamba, Shin'ichi Nojiri
We review cosmology in non-minimal Yang-Mills/Maxwell theory, in which the Yang-Mills/electromagnetic field couples to a function of the scalar curvature. We show that power-law in…
Inflationary cosmology and the late-time accelerated expansion of the universe in non-minimal Yang-Mills- gravity and non-minimal vector- gravity
Kazuharu Bamba, Shin'ichi Nojiri, Sergei D. Odintsov
We study inflationary cosmology and the late-time accelerated expansion of the universe in non-minimal Yang-Mills (YM) theory, in which the YM field couples to a function of the sc…
Hypermagnetic Baryogenesis
Kazuharu Bamba, C. Q. Geng, S. H. Ho
We study a new scenario for baryogenesis due to the spontaneous breaking of the invariance through the interaction between a baryon current and a hypermagnetic helicity. The…
Accelerating Cosmologies in the Einstein-Gauss-Bonnet Theory with Dilaton
Kazuharu Bamba, Zong-Kuan Guo, Nobuyoshi Ohta
We study cosmological solutions in the low-energy effective heterotic string theory, which is the Einstein gravity with Gauss-Bonnet term and the dilaton. We show that the field eq…
Property of the spectrum of large-scale magnetic fields from inflation
Kazuharu Bamba
The property of the spectrum of large-scale magnetic fields generated due to the breaking of the conformal invariance of the Maxwell theory through some mechanism in inflationary c…
Baryon asymmetry from hypermagnetic helicity in dilaton hypercharge electromagnetism
Kazuharu Bamba
The generation of the baryon asymmetry of the Universe (BAU) from the hypermagnetic helicity, the physical interpretation of which is given in terms of hypermagnetic knots, is stud…
