Popis:	The quantum oscillations of population in an optically driven asymmetrical double quantum dot device coupled to phonons are investigated theoretically and an analytical result is obtained. It shows that, even at zero temperature, the phonon effect is considerable. The Rabi frequency and tunneling rate between two dots are renormalized by a factor and its square, respectively. The ideal Rabi oscillation is changed into a beat pattern.
