1. 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
   接著引入更為復(fù)雜的格點(diǎn)能交替變化的超晶格模型，并在此基礎(chǔ)上考察了hamiltonian中交替變化的對(duì)角項(xiàng)對(duì)準(zhǔn)能譜與動(dòng)力學(xué)的影響。
2. 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，我們在雙模相位空間里利用雙模壓縮相干態(tài)所對(duì)應(yīng)的算符定義二類獨(dú)立的相位算符并相應(yīng)求出本征態(tài)，而它的產(chǎn)生算符和湮滅算符是通過簡諧振子的產(chǎn)生算符和湮滅算符經(jīng)過正則變換得到的。
