Constraints on warped compactifications
Masato Minamitsuji, Kunihito Uzawa
We discuss a possible compactification of a higher-dimensional gravitational theory, which give rise to a de Sitter or an accelerating universe, to the extent that it can describe…
Non-minimally coupled hybrid inflation
Seoktae Koh, Masato Minamitsuji
We discuss the hybrid inflation model where the inflaton field is nonminimally coupled to gravity. In the Jordan frame, the potential contains term as well as terms in the or…
Cosmological Kaluza-Klein branes in black brane spacetimes
Masato Minamitsuji
We discuss the comsological evolution of a brane in the -dimensional black brane spacetime in the context of the Kaluza-Klein (KK) braneworld scheme, i.e., to consider KK co…
Instability of brane cosmological solutions with flux compactifications
Masato Minamitsuji
We discuss the stability of the higher-dimensional de Sitter (dS) brane solutions with two-dimensional internal space in the Einstein-Maxwel theory. We show that an instability app…
Cosmological evolution of regularized branes in 6D warped flux compactifications
Masato Minamitsuji, David Langlois
We study the cosmological evolution of extended branes in 6D warped flux compactification models. The branes are endowed with the three ordinary spatial dimensions, which are assum…
Brane cosmological solutions in six-dimensional warped flux compactifications
Tsutomu Kobayashi, Masato Minamitsuji
We study cosmology on a conical brane in the six-dimensional Einstein-Maxwell-dilaton system, where the extra dimensions are compactified by a magnetic flux. We systematically cons…
