M-theory Supertubes with Three and Four Charges
Dongsu Bak, Kyungyu Kim, Nobuyoshi Ohta
Using the covariant M5-brane action, we construct configurations corresponding to supertubes with three and four charges. We derive the BPS equations and study the full structure o…
Time-dependent Solutions with Null Killing Spinor in M-theory and Superstrings
Takayuki Ishino, Hideo Kodama, Nobuyoshi Ohta
Imposing the condition that there should be a null Killing spinor with all the metrics and background field strengths being functions of the light-cone coordinates, we find general…
Intersecting Non-extreme p-Branes and Linear Dilaton Background
Chiang-Mei Chen, Dmitri V. Gal'tsov, Nobuyoshi Ohta
We construct the general static solution to the supergravity action containing gravity, the dilaton and a set of antisymmetric forms describing the intersecting branes delocalized…
Parametrization of Quintessence and Its Potential
Zong-Kuan Guo, Nobuyoshi Ohta, Yuan-Zhong Zhang
We develop a theoretical method of constructing the quintessence potential directly from the effective equation of state function , which describes the properties of the dark…
