等离子体密度对多光子电离的影响

Effects of background plasma density on multi-photon ionization

利用“光学度规”的方法研究了等离子体中的多光子电离 ,获得了“弯曲时空”中的量子Volkov态 .应用量子电动力学的形式散射理论得出了多光子电离的散射截面 .阐述了等离子体密度对发生在其中的多光子电离的“抑制”

Multi-photon ionization (MPI) in plasma which is examined in terms of optical metric and the quantum Volkov state in curved space-time is derived. The cross section of MPI is derived by virtur of the corrected Volkov state within the framework of quantum electrodynamics formal scattering theory. It shows that the plasma medium acts as a “suppression” on MPI.
