Entanglement spectrum of non-Abelian anyons

Non-Abelian anyons can emerge as fractionalized excitations in two-dimensional systems with topological order. One important example is the Moore—Read fractional quantum Hall state. Its quasihole states are zero-energy eigenstates of a parent Hamiltonian, but its quasiparticle states are not. Both of them can be modeled on an equal footing using the bipartite composite fermion method. We study the entanglement spectrum of the cases with two or four non-Abelian anyons. The counting of levels in the entanglement spectrum can be understood using the edge theory of the Moore—Read state, which reflects the topological order of the system. It is shown that the fusion results of two non-Abelian anyons is determined by their distributions in the bipartite construction.     

管内和管束中对流汽化关系式的评价

在计算对流汽化传热系数中使用三种现象学模型，即叠加、渐近和强化模型。这些模型最初都是为管内汽化所提出的，本研究的目的是对这些模型进行评价，从而为修正模型建立适当基础。     

纳米氧化锌颗粒对滨海湿地微生物群落的影响

利用滨海湿地模拟系统研究纳米氧化锌颗粒(ZnO NPs)对滨海湿地周期淹水区和长期淹水区微生物群落组成和多样性的影响，采用16S rRNA扩增子测序查明发生显著性变化的微生物。结果表明：ZnO NPs暴露下微生物群落的相对丰度和多样性均受到不同程度的影响；ZnO NPs质量浓度的大小是驱动滨海湿地环境中微生物群落相对丰度、β多样性变化的重要原因。随着ZnO NPs质量浓度的增大，ZnO NPs团聚后增大的纳米材料颗粒粒径减弱了对微生物群落的影响；β多样性在ZnO NPs质量浓度为80 mg/L时最低；周期淹水区的微生物群落受到的影响比长期淹水区微生物群落受到的影响小，不同淹水条件导致出现不同分类水平的显著差异细菌；周期淹水区和长期淹水区不同的环境条件(如溶解氧、有机质)导致微生物群落丰度、多样性受ZnO NPs的影响表现不同。
