Proposal for geometric generation of a biexciton in a quantum dot using a chirped pulse
arXiv:0806.0148 · doi:10.1103/PhysRevB.78.155315
Abstract
We propose to create a biexciton by a coherent optical process using a frequency-sweeping (chirped) laser pulse. In contrast to the two-photon Rabi flop scheme, the present method uses the state transfer through avoided level crossing and is a geometric control. The proposed process is robust against pulse area uncertainty, detuning, and dephasing. The speed of the adiabatic operation is constrained by the biexciton binding energy.
