We consider the effect of nonmagnetic and magnetic impurities on the superheating field $H_s$ in a type-II superconductor. We solved the Eilenberger equations, which take into account the nonlinear pa...
We used a quantum Monte Carlo method to study the magnetic impurity adatoms on graphene. We found that by tuning the chemical potential we could switch the values of the impurity local magnet moment b...
We present a method for amplifying a single or scattered impurities immersed in a background gas of ultra cold atoms so that they can be optically imaged and spatially resolved. Our approach relies on...
We study striped morphologies induced by magnetic impurities in d-wave superconductors (DSCs) near optimal doping by self-consistently solving the Bogoliubov-de Gennes equations based on the t −...
Mobility of band carriers scattered on donors, partially ionized, partially neutral, is considered in general and calculated for crystals of AIII-BV group. As neutral impurity we have constructed the ...
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state.The fi...
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only two accessible stat...
Results of first principles modelling of interactions graphene and graphite with iron impurities predict the colossal difference between these two carbon allotropes. Insertion of the iron atoms betw...

2005Vol.43No.4pp.743-748DOI: Density of States in Two-Dimensional Square Lattices Around Half Filling with Strong Impurities GU Yu,1 YANG Yong-Hong,1,2 WANG Yong-Gang,1 and ZHANG ...
2004Vol.42No.1pp.126-130DOI: Critical Behavior of Ising Model with Long Range Correlated Quenched Impurities CHEN Yuan Department of Physics, Guangzhou University, Guan...
专著信息 书名 Effects of Zn impurities on the ARPES line shapes of high-Tc superconductors 语种 英文 撰写或编译 作者 D.N.Shi,Z.D.Wang,J.X. Li 第一作者单位 出版社 Physica C371, 69-74 (2002) 出版地 出版日期 2002年 月 日 标准书号 介质类型 页数 字数 开本...
The first-principles molecular cluster discrete variational method (DV) is used to investigate the electronic structure and local magnetic properties of Cr impurities in bcc iron and Fe/Cr interfaces....
We investigate the spin dynamics of a magnetic adatom on a non-magnetic surface with strong Stoner enhancement. We find a strong damping of the adatom’s magnetization precession and a large shift of t...
We study the charge transport by polarons in conjugated polymers in the presence of impurities. The effects on the polaron motion due to the symmetry of the chain is considered. The polaron dynamics i...
