关于Condensed Matter系统多维瞬子形成的最小判据?
Toward a Mininum Criteria of Multi Dimensional Instanton Formation for Condensed Matter Systems?
摘要:
我们的论文概括了最初明确开发的CDW应用程序的技术,只需要什么是多维瞬子形成在复杂的凝聚态物质的应用。这涉及到形成孤子-反孤子对的必要条件,假设电荷中心之间的距离最小,并讨论了以前的密度波物理的例子,为什么一个Pielels间隙项被添加到倾斜的搓板势,以确保标量势场的形成。我们指出,对于高维凝聚态系统,需要同样的方法,给出了Lu提出的二维瞬子的明确参考,并指出在高维中的进一步发展是必要的。
英文摘要:
Our paper generalizes techniques initially explicitly developed for CDW applications only with respect to what is needed for multi dimensional instantons forming in complex condensed matter applications. This involves necessary conditions for formulation of a soliton- anti soliton pair,assuming a minimum distance between charge centers, and discusses the prior density wave physics example as to why a Pierels gap term is added to the tilted washboard potential for insuring the formation of scalar potential fields . We state that much the same methodology is needed for higher dimensional condensed matter systems/ giving an explicit reference to two dimensional instantons as presented by Lu, and indicating further development in higher dimensions is warranted
