基于变分法的光子超导波基态分析

Analysis of Photonic Superguiding Ground States by Variational Method

利用一般的电磁辐射与晶格振动的相互作用模型，研究了强光场与晶格振动的非线性相互作用导致光子对形成这一基本问题，导出了光子．光子有效相互作用。然后利用变分法求得了超导波态系统的基态能量表达式，并讨论了光子对的形成条件。

Using the general model of interaction Hamiltonian of electromagnetic radiation with a crystal lattice,we investigate the formation of photon pairs due to the nonlinear interaction of intense light with lattice vibration,obtaining photon-photon effective interaction. The expression of ground energy is given by means of variational method,and the condition of formation of photon pairs discussed.
