自旋交叉科学研究

Spin-based Interdisciplinary Research

自旋是自然界粒子的基本属性,在现代科技如磁共振影像、磁存储中有着重要应用。近三十年来,随着实验技术的巨大进步,人们对自旋的调控达到了新的高度,现已能在微观尺度上对少量乃至单个自旋进行高精度地控制和测量,为开启全新的自旋应用带来了重大机遇。通过发展新颖的具备变革性特征的自旋科学技术,有望促成前沿交叉科学研究中的重大突破,并催生出一批有可能对人类社会带来深远影响的重要科技。自旋交叉科学的研究已在世界范围内得到高度重视,呈现出各国激烈竞争的局面。本文简要介绍了该领域的主要研究进展、关键问题和发展趋势,并对国际竞争中我国如何巩固和扩大在该领域的优势给出了一些政策性建议。

Spin is an intrinsic property of the particles in nature.Many important applications in modern sciences are based on the effects of spin,such as magnetic resonance imaging and magnetic memory.Over the past thirty years,with the great progresses of experimental technologies,one can now precisely control and measure a few or even a single spin in the microscale,which opens up brand new applications of spin.Those spin-based disruptive technologies being studied may bring breakthroughs in basic sciences through interdisciplinary researches,and further lead to several important realistic applications which will potentially change the human society.Spin-based interdisciplinary research has attracted broad interests and led to intense competitions between the main countries in the world.Here we briefly review the main progresses in this field as well as its key scientific problems and future development tendency.Recommendations on how to keep competitive of our country in this emerging scientific field are provided finally.
