quantum

We study the commutation relations, uncertainty relations and spectra of position and momentum operators within the framework of quantum group % symmetric Heisenberg algebras and their (Bargmann-) Fock representations. As an effect of the underlying noncom

We describe a scheme of quantum mechanics in which the Hilbert space and lin-ear operators are only secondary structures of the theory.As primary structures we consider observables,elements of noncommutative algebra,and the physical states,the nonlinear functionals on this algebra,which associate with results of single mea-sureme

quantum-espresso安装

quantum-espresso（原先叫pwscf）十分容易安装，至少比同类的CPMD, cp2k容易多了，作为一个后起之秀，解决了很多前一代软件安装上的问题。

首先我假定你有一台AMD多核（4核或6核）的台式机，i7-6核更好；当然最好的是1280核的cluster神码的；

其次，必须装Linux, 没听说过在windows下跑quantum-espresso的，就像火车必须上火车道。火车不是不能在大马路上跑，只是那样不叫一个事儿；如果你不会 Linux操作，现学，单机装Ubuntu，上手很快的；如果你从来没装过，马上请周围懂Linux的朋友20分钟即可装好Ubuntu，再学一些基本命令行操作；千万不能被一些本来很容易办到的事情吓住，对吧。

安装过程大致是这样的，1.下载；2.解压；3.编译；4.测试 一步一步来，没有搞不成的； 1.下载

这里我教个更简单的下载方法，打开Ubuntu linux命令行终端窗口terminal，在Linux 命令提示符$或>后面输入： $wget http://qe-forge.org/frs/download.php/167/espresso-4.3.2.ta

After review the quantum Hall effect on the fuzzy two-sphere $S^2$ and Zhang and Hu's 4-sphere $S^4$, the incompressible quantum Hall fluid on $S^2$, $S^4$ and torus are discussed respectively. Next, the corresponding Laughlin wavefunctions on $S^2$ are al

We have studied the tunability of the interaction between permanent dipoles in Bose-Einstein condensates. Based on time-dependent control of the anisotropy of the dipolar interaction, we show that even the very weak magnetic dipole coupling in alkali gases
