Interacting new agegraphic dark energy with power-law corrected entropy in Horava-Lifshitz cosmology
Corrected entropy-area relation New agegraphic dark energy Hoˇrava-Lifshitz cosmology
2011/9/1
We investigate the new agegraphic dark energy (NADE) model with power-law corrected entropy in the framework of Hoˇrava-Lifshitz cosmology. For a non-flat universe containing the interacting power-law...
A solvable model of fracture with power-law distribution of fragment sizes
solvable model power-law distribution Statistical Mechanics
2011/7/27
Abstract: The present paper describes a stochastic model of fracture, whose fragment size distribution can be calculated analytically as a power-law-like distribution. The model is basically cascade f...
Among various scenarios to explain the acceleration of the universe expansion, the holographic dark energy (HDE) model has got a lot of enthusiasm recently. In the derivation of holographic energy de...
We present a perturbative approach for studying inflation models with soft departures from scale free spectra of the power law model. In the perturbed power law (PPL) approach one obtains at the leadi...

Scalar field reconstruction power-law entropy-corrected holographic dark energy
2010/12/24
A so called "power-law entropy-corrected holographic dark energy" (PLECHDE) was recently proposed to explain the dark energy dominated universe. This model is based on the power-law corrections to bl...
Stationary point approach to the phase transition of the classical XY chain with power law interactions
Stationary point power law interactions
2010/11/25
The stationary points of the Hamiltonian H of the classical XY chain with power law pair
interactions (i. e., decaying like r− with the distance) are analyzed. For a class of “spinwave-type”st...
Non-Extensive Black Hole Thermodynamics Estimate for Power-Law Particle Spectra
non-extensive thermodynamics heavy ion collisions black hole evaporation
2010/12/21
We point out that by considering the Hawking-Bekenstein entropy of Schwarzschild black hole
horizons as a non-extensive Tsallis entropy, its additive formal logarithm, coinciding with the Renyi entro...
The exact dynamics of a Jaynes-Cummings model for a qubit interacting with a continuous distribution of bosons, characterized by a special form of the spectral density, is evaluated analytically. The ...
Typical rank of coin-toss power-law random matrices over GF(2)
Typical coin-toss power-law
2010/11/18
Random linear systems over the Galois Field modulo 2 have an interest in connection with problems ranging from computational op-timization to complex networks.
We present a perturbative approach for studying inflation models with soft departures from scale free spectra of the power law model. In the perturbed power law (PPL) approach one obtains at the leadi...
Power-law Distributions in Information Science - Making the Case for Logarithmic Binning
Power-law Distributions Information Science Logarithmic Binning
2010/11/16
We suggest partial logarithmic binning as the method of choice for uncovering the nature of many distributions encountered in information science (IS). Logarithmic binning retrieves information and t...

Power-law ensembles: fluctuations of volume or temperature ?
Power-law ensembles fluctuations of volume temperature
2011/1/10
We present two issues here: (i) that in situation when total energy is kept constant re-cently proposed fluctuations of volume ensemble is equivalent to the approach using Tsallis statistics with fluc...
Power-Law Entropic Corrections to Newton's Law and Friedmann Equations From Entropic Force
Power-Law Entropic Corrections Newton's Law Friedmann Equations
2010/12/21
A possible source of black hole entropy could be the entanglement of quantum fields in and out the horizon. The entanglement entropy of the ground state obeys the area law. However, a correction term ...
