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…
Revisiting the Schrödinger-Dirac equation
Nicolas Fleury, Fayçal Hammad, Parvaneh Sadeghi
In flat spacetime, the Dirac equation is the "square root" of the Klein-Gordon equation in the sense that by applying the square of the Dirac operator to the Dirac spinor, one reco…
Plane-wave and wavepacket neutrino flavor oscillations in vacuum in conformal coupling models
Fayçal Hammad, Parvaneh Sadeghi, Nicolas Fleury
We investigate neutrino flavor oscillations in vacuum within a general conformal coupling model. We first examine the flavor oscillations within the plane-wave description of neutr…
Fresh look at the effects of gravitational tidal forces on a freely-falling quantum particle
F. Hammad, P. Sadeghi, N. Fleury +1
We take a closer and new look at the effects of tidal forces on the free fall of a quantum particle inside a spherically symmetric gravitational field. We derive the corresponding…
What can we learn from the conformal noninvariance of the Klein-Gordon equation?
F. Hammad, P. Sadeghi, N. Fleury +1
It is well known that the Klein-Gordon equation in curved spacetime is conformally noninvariant, both with and without a mass term. We show that such a noninvariance provides nontr…
Local Fractional Supersymmetry for Alternative Statistics
N. Fleury, M. Rausch de Traubenberg
A group theory justification of one dimensional fractional supersymmetry is proposed using an analogue of a coset space, just like the one introduced in supersymmetry. This th…
On Polynomial Relations in the Heisenberg Algebra
N. Fleury, A. Turbiner
Polynomial relations between the generators of the classical and quantum Heisenberg algebras are presented. Some of those relations can have a meaning of the formulas of the normal…
