Abstract: (406 Views)
In this paper, we investigate the entanglement between two-level atoms in the presence of a bilayer structure with parity and time reversal symmetry using the effective medium theory in quantum optics. To do this, we consider two bilayer structures, one of them is composed of identical gain and loss layers and the other one of nonidentical layers. We model dissipation, amplification and dispersion properties of layers with Lorentz model and use effective optical parameters to calculate the electromagnetic Green tensor of the system. Then by calculating the collective damping rates and spontaneous emission rate of atomic subsystem, we obtain the concurrence for the situation that only one of the atoms is excited. It is shown that the atomic system is entangled in larger time interval rather than the systems without the PT-symmetric layers.
