摘要：
本研究探讨了物质波不稳定性对具有任意简并度的电子束输运的影响。我们采用Schrödinger-Poisson（薛定谔-泊松）系统的一类特解，对恒定速度下的电子束输运过程进行建模。研究表明，此类电子束可由一个耦合受驱赝力系统描述，其解会产生具备波粒二象性的等离激元激发。研究发现，量子力学中的基本德布罗意关系源于类粒子等离激元激发分支与电子束漂移之间的共振相互作用。我们进一步推导得到了一种广义的双尺度德布罗意波粒关系，并借助该关系在本模型中研究了多种束-等离激元不稳定性。文中详细讨论了量子电荷屏蔽与化学势对物质波形成及不稳定性的影响，并在当前的量子流体动力学模型中重新探讨了著名的Aharonov-Bohm（阿哈罗诺夫-玻姆）效应。本研究可进一步阐明量子力学中物质波的起源，并助力清晰理解新型波粒相互作用。
英文摘要：
In this research we study the effect of matter-wave instability on electron beam transport with arbitrary degree of degeneracy. Particular class of solutions of the Schrödinger-Poisson system is used to model the electron-beam transport at constant speed. It is shown that such electron-beam is described by a coupled driven pseudoforce system solution of which leads to plasmon excitations with dual wave-particle character. The fundamental quantum mechanical de Broglie relation is found to be due to the resonant interaction of particle-like plasmon excitation branch with the electron beam drift. We further obtain a generalized double lengthscale de Broglie wave-particle relation through which various beam-plasmon instability is studied in this model. The quantum charge screening and the chemical potential effects on the matter-wave formation and instabilities are discussed in detail and the well-known Aharonov-Bohm effect is revisited in current quantum hydrodynamic model. Current research may further illuminate the origin of matter-wave in quantum mechanics and lead to clear understanding of novel wave-particle interactions.
