小恒定电场下预存共振的不稳定性
Instability of pre-existing resonances under a small constant electric field
摘要:
两个简单的模型运营商被认为是预先存在的共振。一个潜在的对应于一个小的电场,$f$,然后引入和由此产生的运营商的共振被认为是$f\to0$。结果表明,这些共振是不连续的,在这个限制。在更复杂的原子和分子模型中也会出现类似的现象。数值结果。
英文摘要:
Two simple model operators are considered which have pre-existing resonances. A potential corresponding to a small electric field, $f$, is then introduced and the resonances of the resulting operator are considered as $f\to0$. It is shown that these resonances are not continuous in this limit. It is conjectured that a similar behavior will appear in more complicated models of atoms and molecules. Numerical results are presented.
