Thirdly we introduce the superlattice model with alternating site energies which is more complicated than the simple tight - binding model , and moreover we explore the influence of the alternating diagonal term in hamiltonian on the quasi - energy bands and dynamics 接着引入更为复杂的格点能交替变化的超晶格模型,并在此基础上考察了hamiltonian中交替变化的对角项对准能谱与动力学的影响。
On the one hand , we deduce the off - diagonal term of reduced density matrix is inner - product of two coherent states and we carry out decoherence in macroscopic limits in two special case , on the other hand , we delay decoherent time by controlling the interaction coefficient . in other part , we define two kind independent phase operators by improving two - mode squeezing coherent states in two - mode phase space and resolve their eigenstates 在第二部分中,我们在双模相位空间里利用双模压缩相干态所对应的算符定义二类独立的相位算符并相应求出本征态,而它的产生算符和湮灭算符是通过简谐振子的产生算符和湮灭算符经过正则变换得到的。
