摘要:

本文研究了一类特殊的含时哈密顿问题H=-{1/2}(t_o/t)^a \partial_{xx} +(1/2)ω^2(t/t_o)^bx^2.这对应于与时间相关的质量(TM)薛定谔方程。我们给出了不同的含时二次薛定谔方程(TQ)和不同的含时振子(TO)方程的具体变换。对于每一个薛定谔系统,我们给出了时空对称性的李代数、数态、压缩态<x>和<p>(以及它们的经典运动)、(Δx)^2、(Δp)^2以及不确定性积。

英文摘要:

We attack the specific time-dependent Hamiltonian problem H=-{1/2} (t_o/t)^a \partial_{xx} + (1/2) ω^2 (t/t_o)^b x^2. This corresponds to a time-dependent mass (TM) Schrödinger equation. We give the specific transformations to a different time-dependent quadratic Schrödinger equations (TQ) and to a different time-dependent oscillator (TO) equation. For each Schrödinger system, we give the Lie algebra of space-time symmetries, the number states, the squeezed-state <x> and <p> (with their classical motion), (Δx)^2, (Δp)^2, and the uncertainty product.
