The role of spin in entanglement generated by expanding spacetime
Roberto Pierini, Shahpoor Moradi, Stefano Mancini
We investigate the effects of spin on entanglement arising in Dirac field in an expanding spacetime characterized by the Robertson-Walker metric. We present a general approach that…
Frame independent nonlocality for three qubit state
Shahpoor Moradi, Mohsen Aghaee
Bell's inequality is investigated for the three qubit GHZ state in relativistic regime. Two different relativistic spin operator are considered. One of them is defined by Lee, and…
Testing quantum nonlocality for three coupled quantum dots within optical microcavity QED
Shahpoor Moradi, Sassan Moradi
Bell's inequality in three coupled quantum dots (QDs) within cavity QED, including Forster and exciton-phonon interactions, is investigated theoretically. For an initially entangle…
Entanglement Generation by Time Varying Refractive Index: Analogy with Cosmological Model
Shahpoor Moradi
Generation of entanglement between modes of a electromagnetic fields by sudden change of the refractive index of a medium is considered. We use the analogy between the Fock-space f…
Cosmological Entanglement
Shahpoor Moradi, Mosleh Rasouli
We investigate the connection between the entanglement generated by expanding universe and the cosmological parameters. We show that the faster the universe expands and the larger…
Bell's inequality for a system composed of particles with different spin
Shahpoor Moradi
For two particles with different spin, we derive the Bell's inequality. The inequality is investigated for two systems combining spin-1 and 1/2; spin-1/2 and 3/2. We show that for…
