这种方法称作含时微扰理论(time-dependent perturbation theory) 2.1 两个能级的系统 对于一个前微扰的不含时的哈密顿 H^0 来说,如果我们讨论的问题仅限于两个量子态(毕竟这样是最简单的,最好入门的) ψa、 ψb ,它们分别是能级 Ea、 Eb( Ea<Eb )的本征态( H^0ψi=Eiψi,i=a,b),它们肯定是正交...

现在回忆一下前面 (4) 式 i\hbar{\partial\hat U(t,t_0)\over\partial t}=\hat H\hat U(t,t_0) ,现在我们把相互作用绘景下的时间演化算符代入并计算 \begin{align} i\hbar{\partial\hat U_0(t,t_0)\hat U_\mathcal I(t,t_0)\over\partial t}&=\hat H\hat U_0(t,t_0)\hat U_...
Inthis chapter, we deal with the quantum transitions between stationary states of a system subjected to a perturbation for a time lapse. The stationary states are described by the time-independent Hamiltonian [Math Processing Error] H 0 \\mathbf{H_0} and the perturbation by the time-dependent...
2) time-dependent perturbation theory 含时微扰论 1. With thetime-dependent perturbation theory,the dynamics of a two-level system coupled to an Bose field is revisited. 从含时微扰论的角度出发,重新求解了与玻色场相耦合的两态系统的动力学。
PERTURBATION THEORYTRANSFORMATIONS (MATHEMATICSPARTIAL DIFFERENTIAL EQUATIONSIt is shown that a given time-dependent solution Ψ( x, t) of a one-electron Schrdinger equation for Hamiltonian H, is also the solution to the Schrdinger equation when a time-dependent perturbation of His added to the ...

Second-Order Time-Dependent Perturbation Theory Let us consider the extension of time-dependent perturbation theory to second order in the interaction H 1 (t). The starting point is the set of differential equations i¯ h da (j+1) n (t) dt = m n|H 1 (t)|m e iωnmt a (j)...
The effects of the periodical time-dependent perturbation on a KdV (Korteweg de Vries) soliton are studied. Expanding the perturbation term into a Fourier series, we find that the time-independent term will lead to the...
