诺贝尔物理学奖40年:过去和现在

40 years of the Nobel prize in physics: then and now

Ricardo A. Broglia

摘要:

Aage Bohr和Ben R.莫特森成为1975年诺贝尔物理学奖的共同获奖者,为原子核结构研究中的中心问题提供了全面和可操作的答案,即确定适合描述所遇到的现象的适当概念和自由度。为了做到这一点,他们产生了一个惊人的统一的一些既定的概念,即液滴和壳模型,基本模式的激发,超导性和量子电动力学,最终导致在范例的对称性破缺恢复,以确定核集体变量(CV,激励的基本模式):平均场和散射态对平移不变性的破坏(单粒子运动),在各种空间中,特别是在3D空间和规范空间中的旋转不变性,导致表面振动和四极旋转,以及配对振动和旋转,在这些空间中伴随着广义刚性的相关涌现性质,这是由与单粒子自由度的耦合引起的。

英文摘要:

The findings for which Aage Bohr and Ben R. Mottelson became co-winners of the 1975 Nobel prize in physics provided the basis for a comprehensive and operative answer to the central problem in the study of the nuclear structure, namely the identification of the appropriate concepts and degrees of freedom that are suitable for describing the phenomena encountered. To do so they produced a breathtaking unification of a number of well established concepts, namely liquid drop and shell models, elementary modes of excitation, superconductivity and quantum electrodynamics, resulting eventually in the paradigm of broken symmetry restoration to determine the nuclear collective variables (CV, elementary modes of excitation): violation of translation invariance by the mean field and by scattering states (single-particle motion), of rotational invariance in the variety of spaces, in particular in 3D- and in gauge-space, leading to surface vibrations and to quadrupole rotations, as well as to pairing vibrations and rotations, with associated emergent properties of generalized rigidity in these spaces, resulting from the coupling to single-particle degrees of freedom.
