交换作用从根本上改变了量子粒子在经典禁戒区的行为:简单模型

Exchange interaction radically changes behavior of a quantum particle in a classically forbidden region: simple model

V. V. Flambaum

摘要:

交换作用强烈影响局域电子轨道和量子隧穿振幅的长程行为,在Hartree-Fock近似下,交换作用产生幂律衰减,而不是通常的大距离指数衰减。为了证明这种效应是真实的(即不是近似的结果),我们考虑一个简单的模型,在这个模型中可以准确地分析不同的效应。其应用包括在参考文献M中考虑的静电电场或激光场对内部电子电离的巨大增强。Ya.阿穆西亚,arxiv:0904.4395

英文摘要:

Exchange interaction strongly influences the long-range behavior of localized electron orbitals and quantum tunneling amplitudes.In the Hartree-Fock approximation the exchange produces a power-law decay instead of the usual exponential decrease at large distances. To show that this effect is real (i.e. not a result of the approximation) we consider a simple model where different effects may be accurately analyzed. Applications include huge enhancement of inner electron ionization by a static electric field or laser field considered in Ref. M. Ya. Amusia, arxiv:0904.4395
