绝热近似不一致吗?

Is the Adiabatic Approximation Inconsistent?

Solomon Duki, H. Mathur, Onuttom Narayan

摘要:

Marzlin和Sanders \cite{marzlin}已经严格地证明,当应用于生成演化$U^{\dagger} (t)$的哈密顿量$H(t)$时,绝热近似可能非常不准确,即使它给出了对由对偶哈密顿量$h(t)$生成的演化$U(t)$的极好近似。我们表明,这是不符合绝热定理,并发现,在一般情况下,即使$h(t)$满足绝热定理的条件,$H(t)$将可能违反这些条件。

英文摘要:

Marzlin and Sanders \cite{marzlin} have shown rigorously that the adiabatic approximation can be very inaccurate when applied to a Hamiltonian $H(t)$ that generates the evolution $U^{\dagger} (t)$ even if it gives an excellent approximation to the evolution $U(t)$ generated by a dual Hamiltonian $h(t)$. We show that this is not inconsistent with the adiabatic theorem and find that in general even if $h(t)$ satisfies the conditions of the adiabatic theorem, $H(t)$ will likely violate those conditions.
