| 1 | Quantum phase transition and entanglement in Li atom system显示文摘By use of the exact diagonalization method, the quantum phase transition and en- tanglement in a 6-Li atom system are studied. It is found that entanglement appears before the quantum phase transition and disappears after it in this exactly solvable quantum system. The present results show that the von Neumann entropy, as a measure of entanglement, may reveal the quantum phase transition in this model. | SI LiMing1 & HOU JiXuan2 1 Department of Electronic Engineering, School of Information Science and Technology, Beijing Institute of Technology, Beijing 100081, China 2 Laboratoire de Chimie, UMR 5182 CNRS, Ecole Normale Supérieure de Lyon, 46, Allée d’Italie, F-69364 Lyon Cedex 07, France | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，11： | 6 |
| 3 | Self-assembly of amphiphilic molecules:A review on the recent computer simulation results显示文摘We provided a short review on the recent progresses in computer simulations of adsorption and self-assembly of amphiphilic molecules.Owing to the extensive applications of amphiphilic molecules,it is very important to understand thoroughly the effects of the detailed chemistry,solid surfaces and the degree of confinement on the aggregate morphologies and kinetics of self-assembly for amphiphilic systems.In this review we paid special attention on(i) morphologies of adsorbed surfactants on solid surfaces,(ii) self-assembly in confined systems,and(iii) kinetic processes involving amphiphilic molecules. | CHEN XiaoMing1,DONG Wei2 & ZHANG XianRen1 1Key Laboratory for Nanomaterials,Ministry of Education Beijing University of Chemical Technology,Beijing 100029,China 2Laboratoire de Chimie,UMR 5182,CNRS,Ecole Normale Supérieure de Lyon,46,Allée d’Italie,69364 Lyon Cedex 07,France | 2010 | Science China Chemistry2010，53，9： | 0 |
