Cherenkov radiation and pair production by particles traversing laser beams
Therefore, we may selectively couple the two initially non-resonant QD’s (satisfying Eq. 5 before the laser is switched on) by the application of a single detuned laser satisfying Eq. 6 which non-adiabatically shifts the eigenstates to the anticrossing point in Fig. 1.
Creating excitonic entanglement in quantum dots through the optical Stark effect
In this case, if the laser is sufficiently detuned from resonance (i.e. if δ = (ω1 −ωl) ≫ Ω/2, with Ω the laser-system coupling), the |αni are still approximate eigenstates and we can employ second order perturbation theory to obtain the energy shift in the separation of the two levels.
Creating excitonic entanglement in quantum dots through the optical Stark effect
QD exciton - laser interaction strengths (which correspond to the Rabi frequency when the laser is resonant with the exciton) of a few meV have been attained in an experiment which measured the optical Stark shift in AlAs/GaAs heterostructures .
