等离子体波的爬梯与自共振加速
Ladder Climbing and Autoresonant Acceleration of Plasma Waves
摘要：
当有界等离子体中的背景密度随时间调制时，离散模式变得耦合。有趣的是，对于适当选择的调制，可以使平均等离子体激元能量以梯状方式增长，实现等离子体激元能量的上转换或下转换。这个可逆过程被认为是量子梯子攀爬效应的经典模拟，因此这个过程的效率和速率可以通过类比盒子中的量子粒子来立即写出。在密集间隔的光谱的限制下，爬梯转变为连续的自共振;等离子体激元然后可以被啁啾背景调制操纵，就像电子被啁啾场自共振操纵一样。通过制定一个通用的拉格朗日框架内的波动动力学，类似的爬梯和自共振效应的预测是可以实现的一般线性波在等离子体和其他介质。
英文摘要：
When the background density in a bounded plasma is modulated in time, discrete modes become coupled. Interestingly, for appropriately chosen modulations, the average plasmon energy might be made to grow in a ladder-like manner, achieving up-conversion or down-conversion of the plasmon energy. This reversible process is identified as a classical analog of the effect known as quantum ladder climbing, so that the efficiency and the rate of this process can be written immediately by analogy to a quantum particle in a box. In the limit of densely spaced spectrum, ladder climbing transforms into continuous autoresonance; plasmons may then be manipulated by chirped background modulations much like electrons are autoresonantly manipulated by chirped fields. By formulating the wave dynamics within a universal Lagrangian framework, similar ladder climbing and autoresonance effects are predicted to be achievable with general linear waves in both plasma and other media.
