Non-commutativity on another Minkowski space-time: Vierbein formalism and Higgs approach
Abolfazl Jafari
We extend the non-commutative coordinates relationship into other than the Minkowski space-time. We clarify the non-commutativity dependency to the geometrical structure. As well a…
Free particle and isotropic harmonic oscillator on a spheroidal surface: the Higgs-like approach
Ali Mahdifar, Ehsan Amooghorban
In this paper, we investigate the dynamics of both free particle and isotropic harmonic oscillator constrained to move on a spheroidal surface using two consecutive projections: a…
Ab initio investigation of magnetic ordering in the double perovskite SrNiWO
Nafise Rezaei, Tayebehsadat Hashemifar, Mojtaba Alaei +3
{\it Ab initio} calculations, GGA/GGA+, are used to propose a spin Hamiltonian for the B-site ordered double perovskite, SrNiWO. Our results show that the exchange i…
Antenna Selection in Full-Duplex Cooperative NOMA Systems
Mohammadali Mohammadi, Zahra Mobini, Himal A. Suraweera +1
We investigate the problem of antenna selection (AS) in full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay assists transmiss…
Photon-added and photon-subtracted coherent states on a sphere
Ali Mahdifar, Ehsan Amooghorban, Maryam Jafari
In this paper, we construct the -photon-added and -photon-subtracted coherent states on a sphere. These states are shown to satisfy the usual conditions of continuity in the…
