我在安德森花园的随机漫步

My Random Walks in Anderson's Garden

G. Baskaran

摘要:

安德森的花园是一幅画提交给菲利普W。1983年,安德森60岁生日前夕。这幅漫画(图1),作者不详,简洁地描绘了安德森1983年以前的一些作品,就像一个盛开的花园。作为安德森论文的狂热读者,在安德森的花园里随意散步已经成为我从研究生时代开始的日常生活的一部分。这对我有很大的帮助,也为我在普林斯顿大学与园丁本人的一次精彩合作做好了准备,这次合作是关于高温铜酸盐和量子自旋液体的共振价键(RVB)理论。结果是丰富的-第一个(RVB平均场)理论的i)量子自旋液体,ii)出射费米表面在莫特绝缘体和iii)超导性掺杂莫特绝缘体。超越平均场论- i)涌现规范场,ii)具有RVB规范场的Ginzbuerg Landau理论,iii)超导圆顶的预测,iv)铜酸盐的非费米液体正常态的早期识别和研究等等。本文总结了我多年的园艺尝试,最后简要总结了我在理论上的努力,将RVB超导理论扩展到包括最近的在高压~ 200 GPa下观察到分子固体H_2S具有很高的Tc ~ 203 K超导性。

英文摘要:

Anderson's Garden is a drawing presented to Philip W. Anderson on the eve of his 60th birthday celebration, in 1983. This cartoon (Fig. 1), whose author is unknown, succinctly depicts some of Anderson's pre-1983 works, as a blooming garden. As an avid reader of Anderson's papers, random walk in Anderson's garden had become a part of my routine since graduate school days. This was of immense help and prepared me for a wonderful collaboration with the gardener himself, on the resonating valence bond (RVB) theory of High Tc cuprates and quantum spin liquids, at Princeton. The result was bountiful - the first (RVB mean field) theory for i) quantum spin liquids, ii) emergent fermi surfaces in Mott insulators and iii) superconductivity in doped Mott insulators. Beyond mean field theory - i) emergent gauge fields, ii) Ginzbuerg Landau theory with RVB gauge fields, iii) prediction of superconducting dome, iv) an early identification and study of a non-fermi liquid normal state of cuprates and so on. Here I narrate this story, years of my gardening attempts and end with a brief summary of my theoretical efforts to extend RVB theory of superconductivity to encompass the recently observed very high Tc ~ 203 K superconductivity in molecular solid H2S at high pressures ~ 200 GPa.
