光机械耦合阵列腔系统的量子性质研究

The study of quantum properties in opto-mechanical cavity is the forefront for both the quantum optics and the nanotechnology. Introducting coupled cavity arrays to the opto-mechanical system, not only the original quantum peroperties will be changed, but also the new physical connotations will be achieved. The research in this field is in its beginning stage in the world. For these reasons, this project will study the quantum properties in the hybrid system of the coupled cavity arrays combined with the opto-mechanical resonator (opto-mechanical coupled cavity arrays). The main contents of this project are the follows: 1) developing the quantum theory for the interaction between the coupled cavity arrays and the opto-mechanical resonator; studying the nonlinear effect in the opto-mechanical coupled cavity arrays; 2) analysing the Hamiltonian and the energy strcuture, studying how the coupled cavity arrays affect the intrinsic quantum properties of opto-mechanical cavity, e.g. opto-mechanically induced transparancy, photon bolckade and slow light effects; 3) searching the special quantum properties in opto-mechanical coupled cavity arrays system. Moreover, the applicant have studied the precision measurement based on opto-mechanically induced transparency and nano-mechanical cooling deeply and systematically .In addition, this project is based on both theroy and experiment, it not only can help us to understand the quantum character of opto-mechanical coupled cavity arrays, but also can give the theroy supports to oberseve the quantum properties in opto-mechanical coupled cavity arrays.
