Geometric properties of two-dimensional O(n) loop configurations
Chengxiang Ding, Xiaofeng Qian, Youjin Deng +2
We study the fractal geometry of O() loop configurations in two dimensions by means of scaling and a Monte Carlo method, and compare the results with predictions based on the Co…
Time-Dependent Density Functional Theory with Ultrasoft Pseudopotential: Real-Time Electron Propagation across Molecular Junction
Xiaofeng Qian, Ju Li, Xi Lin +1
A practical computational scheme based on time-dependent density functional theory (TDDFT) and ultrasoft pseudopotential (USPP) is developed to study electron dynamics in real time…
Critical line of an n-component cubic model
Wenan Guo, Xiaofeng Qian, Henk W. J. Blöte +1
We consider a special case of the n-component cubic model on the square lattice, for which an expansion exists in Ising-like graphs. We construct a transfer matrix and perform a fi…
The triangular Ising model with nearest- and next-nearest-neighbor couplings in a field
Xiaofeng Qian, Henk W. J. Bloete
We study the Ising model on the triangular lattice with nearest-neighbor couplings , next-nearest-neighbor couplings , and a magnetic field . This wor…
Critical frontier of the triangular antiferromagnet in a field
X. F. Qian, M. Wegewijs, H. W. J. Bloete
We study the critical line of the triangular Ising antiferromagnet in an external magnetic field by means of a finite-size analysis of results obtained by transfer-matrix and Monte…
