Generation of the CMB cosmic Birefringence through Axion-like particles, Sterile and Active neutrinos
Somayyeh Mahmoudi, Mahdi Sadegh, Jafar Khodagholizadeh +3
The cosmic birefringence (CB) angle refers to the rotation of the linear polarization plane of Cosmic Microwave Background (CMB) radiations when parity-violating theories are consi…
Neutrinos as a probe of curvature
Jafar Khodagholizadeh
Neutrinos, as the anisotropic stress tensor, have a damping effect on the tensor mode perturbation from inflation to the dominated era. First, we study the squared amplitude r…
Gravitational Waves in a Closed Spacetime via Deviation Equation
Jafar Khodagholizadeh, Amir H. Abbassi, Ali Vahedi +1
Within the closed universe, we obtain the amplitude and frequency of gravitational waves in the terms of discrete wave numbers, wave propagation time, and cosmological constant usi…
Aschenbach effect for spinning particles in Kerr-(A)dS spacetime
Ali Vahedi, Jafar Khodagholizadeh, Arman Tursunov
A non-monotonic behavior of the velocity gradient of a test particle revolving around a rapidly rotating black hole in the locally non-rotating frame of reference is known as the A…
Aschenbach effect for spinning particles in Kerr spacetime
Jafar Khodagholizadeh, Volker Perlick, Ali Vahedi
The orbital velocity profile of circular timelike geodesics in the equatorial plane of a Kerr black hole has a non-monotonic radial behavior, provided that the spin parameter o…
Relativistic generalization of the Born rule
Mohammad Javad Kazemi, Mohammad Hosein Barati, Yahya Rokni +1
We have shown that the Born rule is inconsistent with Lorentz symmetry of the Salpeter equation (square root Klein-Gordon equation). So we find relativistic modificat…
