Research Abstract

In this contribution, we investigate the bipartite non-classical correlations (NCCs) of a system formed
by two nitrogen-vacancy (N-V) centers placed in two spatially separated single-mode nanocavities
inside a planar photonic crystal (PC). The physical system is mathematically modeled by timedependent
Schrödinger equation and analytically solved. The bipartite correlations of the two N-V
centers and the two-mode cavity have been analyzed by skew information, log-negativity, and Bell
function quantifiers. We explore the effects of the coupling strength between the N-V-centers and
the cavity fields as well as the cavity-cavity hopping constant and the decay rate on the generated
correlation dynamics. Under some specific parameter values, a large amount of quantum correlations
is obtained. This shows the possibility to control the dynamics of the correlations for the NV-centers
and the cavity fields.
