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 of power-law entropy-corrected holographic dark energy
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...
We study the classical second law of black hole thermodynamics, for Lovelock theories (other than General Relativity), in arbitrary dimensions.Using the standard formula for black hole entropy, we con...
Oedometric Test, Bauer's Law and the Micro-Macro Connection for a Dry Sand
Oedometric Test Micro-Macro Connection

What is the relationship between the macroscopic parameters of the constitutive equation for a granular soil and the microscopic forces between grains? In order to investigate this connection.
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...
We show that the law of the overall supremum $\bar{X}_t=\sup_{s\le t}X_s$ of a L\'evy process $X$ before the deterministic time $t$ is equivalent to the average occupation measure $\mu_t(dx)=\int_0^t...

the Gram's Law in the Theory Riemann Zeta Function
2010/11/23
Some statements concerning the distribution of imaginary parts of zeros of the Riemann zeta\,-function are established. These assertions are connected with so\,-called `Gram's law' or `Gram's rule'. I...

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...
We derive Fourier's law for a completely coherent quantum system coupled locally to two heat baths at different temperatures. We solve the master equation to first order in the temperature difference....
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 ...
We establish the relation between two objects: an integrable system related to Painleve II equation, and the symplectic invariants of a certain plane curve \Sigma_{TW} describing the average eigenvalu...
A constitutive law for cross-linked actin networks by homogenization techniques

Inspired by experiments on the actin driven propulsion of micrometer sized beads we develop and study a minimal mechanical model of a two-dimensional network of stiff elastic filaments grown from the ...
