Quantum coherence and Leggett-Garg inequality
A. Jalal, S. M. Fazeli, M. M. Ettefaghi
In this paper, we attempt to establish the relationship between quantum coherence and the violation of the Leggett-Garg inequality. In particular, employing the Lindblad equation,…
Annihilation of singlet fermionic dark matter into two photons via pseudo-scalar mediator
M. M. Ettefaghi, R. Moazzemi, M. Yazdani Najafabadi
We consider the indirect detection of dark matter within an extension of the standard model (SM) including a singlet fermion as cold dark matter (CDM) and a singlet pseudo-scalar a…
Mixed states for neutral current neutrino oscillation
M. M. Ettefaghi, Z. Askaripour Ravari
The theory of neutrino oscillation predicts that if both neutrino and antineutrino coming from decay are detected, one can observe an oscillation pattern between the correspo…
Quantum coherence in neutrino oscillation in matter
Z. Askaripour Ravari, M. M. Ettefaghi, S. Miraboutalebi
A closer and more detailed study of neutrino oscillation, in addition to assisting us in founding physics beyond the standard model, can potentially be used to understand the funda…
Kink properties in Lorentz-violating scalar field theory
Reza Moazzemi, Mohammad Mehdi Ettefaghi, Amirhosein Mojavezi
We consider topological defects for the theory in (1+1) dimensions with a Lorentz-violating background. It has been shown, by M. Barreto et al. (2006) \cite{barreto2006defec…
Quantum Correlations in Neutrino Oscillation: Coherence and Entanglement
M. M. Ettefaghi, Z. S. Tabatabaei Lotfi, R. Ramezani Arani
In this paper, we consider the quantum correlations, coherence and entanglement, in neutrino oscillation. We find that the -norm as a coherence measure is equal to sum of th…
