Shock wave冲浪加速

Shock wave surfing acceleration

A. A. Vasiliev

摘要:

研究了相对论带电粒子在均匀磁场和斜向传播的静电冲击波中的动力学问题。该系统被简化为一个具有慢变量和快变量的两自由度Hamilton系统。在该系统中,可以发生捕获共振的现象。在一定条件下,捕获的相点永远保持捕获状态。这对应于粒子的无限冲浪加速度。预印本是D.Ucer和V.D.Shapiro(Phys.Rev.Lett.,第87卷,075001,2001),用于Physical Reviews Letters的评论部分。

英文摘要:

Dynamics of a charged relativistic particle in a uniform magnetic field and an obliquely propagating electrostatic shock wave is considered. The system is reduced to a two degrees of freedom Hamiltonian system with slow and fast variables. In this system, the phenomenon of capture into resonance can take place. Under certain condition, a captured phase point stays captured forever. This corresponds to unlimited surfing acceleration of the particle. The preprint is a more detailed version of a comment on the paper by D.Ucer and V.D.Shapiro (Phys.Rev.Lett., vol. 87, 075001, 2001), intended for the Comments section of Physical Reviews Letters.
