诺贝尔物理学奖荣获者杨振宁回母校清华大学定居,以82岁高龄为大一学生讲物理课是中国高等教育从未有过的重大事件;其意义何在?需要从他近年两件言行去寻思。 相似文献

The study of quantum mechanical few-body systems is a century old pursuit relevant to countless subfields of physics. While the two-body problem is generally considered to be well-understood theoretically and numerically, venturing to three or more bodies brings about complications but also a host of interesting phenomena. In recent years, the cooling and trapping of atoms and molecules has shown great promise to provide a highly controllable environment to study few-body physics. However, as is true for many systems where few-body effects play an important role the few-body states are not isolated from their many-body environment. An interesting question then becomes if or (more precisely) when we should consider few-body states as effectively isolated and when we have to take the coupling to the environment into account. Using some simple, yet non-trivial, examples I will try to suggest possible approaches to this line of research. 相似文献

本刊去年第11期介绍过2005年诺贝尔物理学奖.历次诺贝尔奖宣布后,争议时有发生,本次也如此.应本刊特别邀请,我国留美物理学家励名强教授介绍他在这一领域的首创性研究成果及其经历.本文不仅深入浅出地介绍了量子光学与高精密原子光谱的物理原理和物理图像,而且提出了在研究方法、研究思路上也应创新,即作者提出的要走自己的路.当我们对诺贝尔奖与华人科学家再次擦肩而过感到惋惜的同时,也要思考在物理教学中如何培养学生的首创精神.[编者按] 相似文献
