这些天被各种渠道安利Julia,又见到哥们在复现一篇文献1结果,用MATLAB写得很脏,于是进行了Julia初体验,感觉非常不错。这也是我新配的电脑第一次(在没有打开steam的状态下)把八核十六线程跑满,生产力的香气从机箱里溢出来,值得祝贺(x Zhang, Yan-Yang, et al...

An interesting variational principle, first promoted by Bogoliubov. Might be helpful in understanding the origin of Mean Field Theory.

基本群可以用来区分一些拓扑空间,例如球面和环面,甚至可以证明基本群可以用来区分比较general case下的二维曲面,但有着更多的情况基本群无法做出区分。这里说明对于一大类拓扑空间 (i.e. triangulable space), Simplicial Homology Group可以作为一个更精细的拓扑不...

今天,小编给大家分享一份原创居家物理实验,这个实验的特点在于,竟然只需要手机、被子、和床就可以完成(所以这个实验约等于我每天的咸鱼生活了),是不是很神奇呢!一起来看一下吧:
http://blog.czarja.tk/2020/08/20/Quantum-Supermacy-via-Boson-Sampling.html
追寻通用量子计算的过程道阻且长,需要定一些短期的小目标来给大伙儿点动力,Quantum Supremacy 就是其中最小的一个目标,想法是:寻找一个量子体系,经过演化之后测量其结果。将这个过程放在经典计算机上来模拟,如果目前的超算很久才能算出来,就算是“霸权”了。近些年比较火的此类实验有潘建伟领导课题组在线性光学...

氢原子选择定则这个问题乍看很简单,以为不过是给定两个态$\ket{nlm}, \ket{n’l’m’}$,问跃迁矩阵元什么时候可能不是零。

线性响应理论量子多体中涉及的线性响应理论,用来解决这样一个问题:有某个体系,假设其哈密顿量是$H_0$。体系原本有一个密度算符$\rho_0 = e^{-\beta H_0}/Z_0$,沿着自己既定的道路演化。在加上一个含时微扰后,体系的任一个可观测量$A$,其期望值(系综平均)也会相应地随时间改变,将这个改变近...

刘院(以下简称liu)名下的物院神课“李群与李代数”,久闻大名,这学期以身试法,上课体验却实在一言难尽。究其原因,liu基本是按韩其智《物理学中的群论》一书来讲的,此书逻辑链清晰,但大量重要命题没有证明,且存在逻辑跳步;liu的补充材料内容详实,但编排顺序常和认知顺序相悖,很多地方没有说清;再者,李代数整套理论包...
