Numerical Study on the Two-Dimensional Vortex System with Random Pinning

Autor: Zhengkuan Jiao, Ya-bin Yu, Yi-gang Cao

Publikováno v: Chinese Physics Letters. 16:689-691

We study numerically the dynamic behavior of the two-dimensional vortex lattice, moving in a random pinning potential under the action of an external driving force. Different densities of randomly distributed pointlike pinning centers and different v

Path Integral Approach for Multi-dimensional Polarons in a Symmetric Quantum Dot

Autor: Zhengkuan Jiao, Qing-Hu Chen, Yuhang Ren, Yi-gang Cao

Publikováno v: Chinese Physics Letters. 15:585-587

Within the framework of Feynman-Haken path-integral theory, the general expression of the ground-state energy for multi-dimensional polarons in symmetric quantum dots for arbitrary electron-phonon coupling constants are derived. Moreover, in the weak

Publikováno v: Journal of Zhejiang University. Science. 5(5)

Systematic studies of the transport properties of La0.67Ca0.33Mn1−xFe x O3 (x=0–0.3) systems showed that with increasing Fe-doping contentx the resistance increases and the insulator-metal transition temperature moves to lower temperature. For sm
