A Survey through Conformal Time
Tahereh Aeenehvand, Ahmad Shariati
We revisit conformal time in a spatially flat Friedmann--Robertson--Walker universe and use a -dimensional setting as a technically transparent pedagogical arena. Our purp…
Relativistic frequency shifts in a rotating waveguide
M. Khorrami, A. H. Fatollahi, A. Shariati
A photon source is located in a rotating waveguide. An absorber with a sharp absorbing frequency absorbs some of the emitted photons. This decreases the number of photons which are…
Modified Inertia as Nonconservative Newtonian Dynamics
Ahmad Shariati, Nosratollah Jafari
Modified Newtonian dynamics by Milgrom is a paradigm for explaining the rotation curves of spiral galaxies and various other large scale structures. This paradigm includes several…
Decoherence in quantum systems in a static gravitational field
Ahmad Shariati, Mohammad Khorrami, Farhang Loran
A small quantum system is studied which is a superposition of states localized in different positions in a static gravitational field. The time evolution of the correlation between…
Closedness of orbits in a space with SU(2) Poisson structure
Amir H. Fatollahi, Ahmad Shariati, Mohammad Khorrami
The closedness of orbits of central forces is addressed in a three dimensional space in which the Poisson bracket among the coordinates is that of the SU(2) Lie algebra. In particu…
On the relation between the spin and the magnetic moment of the proton
Amir H. Fatollahi, Ahmad Shariati, Mohammad Khorrami
In the context of the quark model of hadrons the spin and the magnetic moment of proton can not be taken proportional. This is in contradiction with the widely used relation betwee…
