Abstract

The quench dynamics of strongly interacting bosons on quartic and sextic traps are studied by exactly solving the time-dependent many-boson Schrödinger equation numerically. The dynamics are addressed by the key measures of one-body density in conjugate space and information entropy. For both cases, rich many-body dynamics are exhibited and the loss of the Bose–Fermi oscillation in the Tonks–Girardeau limit is also attributed.

一维非谐波陷阱中唐克斯-吉拉尔多气体的淬火动力学

通过数值精确求解随时间变化的多玻色子薛定谔方程，研究了强相互作用玻色子在四元和六元陷阱上的淬火动力学。动力学的关键指标是共轭空间中的单体密度和信息熵。在这两种情况下，都表现出了丰富的多体动力学，而且在唐克斯-吉拉尔多（Tonks-Girardeau）极限中的玻色-费米振荡也被归因于此。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
