Quantum dynamics of electric-dipole coupled defect centers in solids

Feng Tang,Lei-Ming Zhou,Nan Zhao

Figure 2. System configuration and calculation parameters. Defect A is located at the origin and defect B is placed in the z-axis with a displacement vector ${\boldsymbol{R}}=(0,0,50)$ nm. The electric dipoles are all along the $\hat{x}$ direction which are denoted by ${{\boldsymbol{d}}}_{A}$ and ${{\boldsymbol{d}}}_{B}$. The magnitude of the dipole is taken to be $| {{\boldsymbol{d}}}_{A}| =| {{\boldsymbol{d}}}_{B}| =| {\boldsymbol{d}}| ={{ea}}_{0}$, where e is the electron charge and a0 is the Bohr radius. The parameter S is chosen to be S = 0.1.
