Carrier induced ferromagnetism in diluted local-moment systems
Guixin Tang, Wolfgang Nolting
The electronic and magnetic properties of concentrated and diluted ferromagnetic semiconductors are investigated by using the Kondo lattice model, which describes an interband exch…
Potential super-hard Osmium di-nitride with fluorite structure: First-principles calculations
Chang-Zeng Fan, Song-Yan Zeng, Li-Xin Li +4
We have performed systematic first-principles calculations on di-carbide, -nitride, -oxide and -boride of platinum and osmium with the fluorite structure. It is found that only PtN…
Low compressible noble metal carbides with rock-salt structure: ab initio total energy calculations of the elastic stability
Chang-Zeng Fan, Song-Yan Zeng, Zai-Ji Zhan +4
We have systematically studied the mechanical stability of all noble metal carbides with the rock-salt structure by calculating their elastic constants within the density function…
Analysis of pion elliptic flows and HBT interferometry in a granular quark-gluon plasma droplet model
Wei-Ning Zhang, Yan-Yu Ren, Cheuk-Yin Wong
In many simulations of high-energy heavy-ion collisions on an event-by-event analysis, it is known that the initial energy density distribution in the transverse plane is highly fl…
The discrete fractional random cosine and sine transforms
Zhengjun Liu, Qing Guo, Shutian Liu
Based on the discrete fractional random transform (DFRNT), we present the discrete fractional random cosine and sine transforms (DFRNCT and DFRNST). We demonstrate that the DFRNCT…
A discrete fractional random transform
Zhengjun Liu, Haifa Zhao, Shutian Liu
We propose a discrete fractional random transform based on a generalization of the discrete fractional Fourier transform with an intrinsic randomness. Such discrete fractional rand…
