在磁场中运动的原子离子的量子能流

Quantum energy flow in atomic ions moving in magnetic fields

Vladimir Melezhik, Peter Schmelcher

摘要:

结合半经典和新近发展的波包传播技术,我们发现了高激发态离子在磁场中运动的量子自电离过程,其起源是能量从质心转移到电子运动。它服从的时间尺度比相应的经典过程大几个数量级。重要的是,发现并分析了导致电离信号间歇行为的量子相干性现象。建立了电离过程的普遍性质。

英文摘要:

Using a combination of semiclassical and recently developed wave packet propagation techniques we find the quantum self-ionization process of highly excited ions moving in magnetic fields which has its origin in the energy transfer from the center of mass to the electronic motion. It obeys a time scale by orders of magnitude larger than the corresponding classical process. Importantly a quantum coherence phenomenon leading to the intermittent behaviour of the ionization signal is found and analyzed. Universal properties of the ionization process are established.
