Dark Energy and Modified Gravities
Shin'ichi Nojiri
We review the several models of the dark energy, which may generate the accelerated expansion of the present universe. We also discuss the the Big Rip singularity, which may occur…
Higher Derivative Gravities and Negative Entropy
Shin'ichi Nojiri
We investigate the black hole solutions in the -gravity, where the action contains the square of the curvature. In case that the action does not contain the square of the Riem…
The de Sitter/Anti- de Sitter Black Holes phase transition?
Shin'ichi Nojiri, Sergei D. Odintsov
We investigate the Schwarzschild-Anti-deSitter (SAdS) and SdS BH thermodynamics in 5d higher derivative gravity. The interesting feature of higher derivative gravity is the possibi…
Is the Chiral Model equivalent to Wess-Zumino-Witten Model when coupled with Gravity?
Shin'ichi Nojiri
We investigate the non-abelian -duality of Wess-Zumino-Witten model. The obtained dual model is equivalent to the model dual to the chiral model found by Curtright-Zacho…
Swimming of Microorganism and the String- and Membrane- like Algebra
Masako Kawamura, Akio Sugamoto, Shin'ichi Nojiri
Swimming of microorganisms is further developed from a viewpoint of strings and membranes swimming in the incompressible fluid of low Reynolds number. In our previous paper the fla…
Black Hole from Black Hole in Two Dimensions
Shin'ichi Nojiri, Ichiro Oda
We present a new class of quantum two dimensional dilaton gravity model, which is described by gauged Wess-Zumino-Witten model deformed by -operator. We analy…
