摘要

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。

Quench dynamics of a Tonks-Girardeau gas in one dimensional anharmonic trap

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.
