时间周期扰动下束缚态的衰变:一个玩具例子

Decay of a Bound State under a Time-Periodic Perturbation: a Toy Case

Michele Correggi, Gianfausto Dell'Antonio

摘要:

研究了初始处于束缚态的三维量子粒子在具有"强度“(α(t))的时间周期零程相互作用作用下的时间演化.在(α(t))的Fourier系数很弱的一般条件下,我们证明了完全电离为(\to \infty).我们还证明了,在相同的条件下,系统的所有状态是散射态。

英文摘要:

We study the time evolution of a three dimensional quantum particle, initially in a bound state, under the action of a time-periodic zero range interaction with ``strength'' (α(t)). Under very weak generic conditions on the Fourier coefficients of (α(t)), we prove complete ionization as (t \to \infty). We prove also that, under the same conditions, all the states of the system are scattering states.
