爱因斯坦有关德育的思想及其当代意义

20世纪伟大的科学家爱因斯坦面对道德衰落和德育式微,从他的关系本位的人学理论出发,提出培养和谐发展的人以建立和谐美好的人际关系,主张在关系中进行德育。这些观点对于21世纪道德教育,仍具有现实意义。德育应基于关系、通过关系、为了关系而展开,应尊重个人、尊重差异、尊重个性。

爱因斯坦固体在“熵和热力学第二定律”教学中的应用

以M icrosoft Excel为计算工具,对爱因斯坦固体模型进行定量分析,以此引出熵的统计定义并将其与热力学第二定律联系起来,为熵和热力学第二定律的教学提供了一种较为有效的方法.与传统的从宏观热力学角度讨论熵的教学方法相比,这种方法显得更加具体直观.

Opto-Mechanical Effects in Superradiant Light Scattering by Bose-Einstein Condensate in an Optical Cavity

We investigate the effects of a movable mirror (cantilever) of an optical cavity on the superradiant light scattering from a Bose-Einstein condensate (BEC) in an optical lattice. We show that the mirror motion has a dynamic dispersive effect on the cavity-pump detuning. Varying the intensity of the pump beam, one can switch between the pure superradiant regime and the Bragg scattering regime. The mechanical frequency of the mirror strongly influences the time interval between two Bragg peaks. We find that when the system is in the resolved side band regime for mirror cooling, the superradiant scattering is enhanced due to coherent energy transfer from the mechanical mirror mode to the cavity field mode.
