相互作用粒子系统的呼吸模式
Breathing mode for systems of interacting particles
摘要:
我们研究了相互作用粒子系统中的呼吸模式。我们的方法,基于Bogolyubov-Born-Green-Kirkwood-Yvon(BBGKY)层次结构的第一个方程中的动力学分析,使我们能够在线性和非线性水平上同时处理广泛的幂律相互作用和相互作用强度。这既把分散在文献中的各种结果放在一个共同的框架中,又通过广泛地推广这些结果,强调了这种呼吸模式的普遍特征。我们的研究结果得到了直接数值模拟的支持。
英文摘要:
We study the breathing mode in systems of trapped interacting particles. Our approach, based on a dynamical ansatz in the first equation of the Bogolyubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy allows us to tackle at once a wide range of power law interactions and interaction strengths, at linear and non linear levels. This both puts in a common framework various results scattered in the literature, and by widely generalizing these, emphasizes universal characters of this breathing mode. Our findings are supported by direct numerical simulations.
