Quantum fluctuations in planar domain-wall space-times: A possible origin of primordial preferred direction
Quantum fluctuations planar domain-wall space-times possible origin primordial preferred direction
2011/10/18
We study the gravitational effects of a planar domain wall on quantum fluctuations of a massless scalar field during inflation. By obtaining an exact solution of the scalar field equation in de Sitter...
A Detailed Study on the Range Fluctuations of $10^{11}$eV to $10^{18}$eV Muons in Water and the Fluctuations of the Cherenkov Lights due to the Accompanied Cascade Showers initiated by Muons

The validity of our Monte Carlo simulation procedure ({\it the integral method}) had been verified by the corresponding analytical procedure of which is quite independent of our method methodologicall...
The Signatures of Large-scale Temperature Fluctuations in the Lyman-alpha Forest
Large-scale Temperature Fluctuations the Lyman-alpha Forest
2011/1/11
It appears inevitable that reionization processes would have produced large-scale temperature fluctuations in the intergalactic medium. Using toy temperature models and detailed heating histories in c...
The impact of spatial fluctuations in the ultra-violet background on intergalactic carbon and silicon
methods: numerical intergalactic medium quasars absorption lines
2010/11/12
Spatial inhomogeneities in the spectral shape of the ultra-violet background (UVB) at the tail-end of He II reionisation are thought to be the primary cause of the large fluctuations observed in the H...
The depth of maximum shower development and its fluctuations: cosmic ray mass composition at E_0 >= 10^17 eV
High Energy Astrophysical Phenomena (astro-ph.HE)

We present new data on Cherenkov light observations obtained during the period 1994-2009, after a modernization of the Yakutsk EAS array. A complex analysis of $\xmax$ and its fluctuations $\sigma(\xm...
The Nature of Primordial Fluctuations from Anisotropic Inflation
Primordial Fluctuations Anisotropic Inflation
2010/3/9
We study the statistical nature of primordial fluctuations from an anisotropic inflation which is realized by a vector field coupled to an inflaton. We find a suitable gauge, which we call the canonic...
In this paper we investigate the power spectrum of thermal fluctuations in very early stage of viscous cosmology. When the state parameter as well as the viscous coefficient of a barotropic fluid is p...
Towards a Holographic Description of Inflation and Generation of Fluctuations from Thermodynamics
Verlinde conjectured entropic force gravity
2010/3/19
Recently, Verlinde conjectured that gravity may be an entropic force, arising from thermodynamics on the holographic screen. We investigate the implications of the entropic force formalism for inflati...
