The quantum Hall effect under the influence of gravity and inertia: A unified approach
Alexandre Landry, Fayçal Hammad, Reza Saadati
The quantum Hall effect under the influence of gravity and inertia is studied in a unified way. We make use of an algebraic approach, as opposed to an analytic approach. We examine…
Neutrino spin oscillation in screening models revisited
Fayçal Hammad, Nicolas Fleury, Parvaneh Sadeghi
We study, using the Mathisson-Papapetrou-Dixon equations, the spin oscillation of neutrinos when the latter are coupled to the scalar field of screening models of dark energy. Firs…
Neutrino flavor oscillations inside matter in conformal coupling models
Fayçal Hammad, Parvaneh Sadeghi, Nicolas Fleury
We recently studied neutrinos flavor oscillations in vacuum within conformal coupling models. In this paper, we extend that analysis by investigating neutrino flavor oscillations i…
Spin-1/2 particles under the influence of a uniform magnetic field in the interior Schwarzschild solution
Fayçal Hammad, Alexandre Landry, Parvaneh Sadeghi
The relativistic wave equation for spin-1/2 particles in the interior Schwarzschild solution in the presence of a uniform magnetic field is obtained. The fully relativistic regime…
Influence of the dispersion relation on the Unruh effect according to the relativistic Doppler shift method
F. Hammad, A. Landry, D. Dijamco
We examine the influence of the dispersion relation on the Unruh effect by Lorentz boosting the phase of Minkowski vacuum fluctuations endowed with an arbitrary dispersion relation…
A fresh look at the influence of gravity on the quantum Hall effect
F. Hammad, A. Landry, K. Mathieu
We study the quantum Hall effect inside a gravitational field. First, we review the influence of the gravitational field of the Earth on the quantum Hall effect. Taking the gravita…
Conformal mapping of the Misner-Sharp mass from gravitational collapse
Fayçal Hammad
The conformal transformation of the Misner-Sharp mass is reexamined. It has recently been found that this mass does not transform like usual masses do under conformal mappings of s…
-Modified Gravity, Wald Entropy, and the Generalized Uncertainty Principle
Fayçal Hammad
Wald's entropy formula allows one to find the entropy of black holes' event horizon within any diffeomorphism invariant theory of gravity. When applied to general relativity, the f…
Radiative Corrections in the (Varying Power)-Law Modified Gravity
Fayçal Hammad
Although the (varying power)-law modified gravity toy model has the attractive feature of unifying the early and late-time expansions of the Universe, thanks to the peculiar depend…
Modified gravity from an entropy functional
Fayçal Hammad
We extend Padmanabhan's entropy functional formalism to show that, in addition to the Gauss-Bonnet or the entire series of Lanczos-Lovelock Lagrangians already obtained, more gener…
A (varying power)-law modified gravity
Fayçal Hammad
In the present paper we analyze a toy model for an gravity which has the form of a power-law modified gravity in which the exponent is space-time dependent. Namely, we inv…
A note on the effect of the cosmological constant on the bending of light
Fayçal Hammad
We take another look at the equations behind the description of light bending in a Universe with a cosmological constant. We show that even within the impact parameter entering int…
Erratum to: An Entropy Functional for Riemann-Cartan Space-Times
Fayçal Hammad
We correct the entropy functional constructed in Int. J. Theor. Phys. 51:362 (2012). The 'on-shell' functional one obtains from this correct functional possesses a holographic stru…
