Random phase approximation (RPA) was proposed by Bohm and Pines in four seminal papers during 1951-1953 to describe the correlation of fermions, namely the correction to the Hartree-Fock theory. While...
The bold diagrammatic Monte Carlo (BDMC) method performs an unbiased sampling of Feyn- man's diagrammatic series using skeleton diagrams. For lattice models the eciency of BDMC can be dramatically im...
提出一种改进的均值偏移(mean shift, MS)目标跟踪算法,用于提高模板漂移和大面积遮挡情况下视觉目标跟踪算法的鲁棒性和准确性。首先判断目标是否存在遮挡现象,当遮挡未发生时,采用原始MS算法跟踪目标,利用选择性分量更新策略对目标模板进行更新,减少模板漂移的影响|当遮挡发生后,利用非对称核函数模型对候选目标模型进行矫正,降低遮挡像素点对MS矢量和目标跟踪稳定性的影响。实验结果表明,改进的跟踪...
We consider the mean-field classical Heisenberg model and obtain detailed information about the magnetization by studying the model on a complete graph and sending the number of vertices to infinity. ...
We study whether the neutron skin thickness $\Delta r_{np}$ of ${}^{208}$Pb originates from the bulk or from the surface of the neutron and proton density distributions in mean field models.
We give a brief overview of recent work examining the presence of $\alpha$-clusters in light nuclei within the Skyrme-force Hartree-Fock model. Of special significance are investigations into $\alpha$...
Abstract: A stochastic treatment yielding to the derivation of a general Fokker-Planck equation is presented to model the slow convergence towards equilibrium of mean-field systems due to finite-N eff...
Since roughly a decade ago, network science has focussed among others on the problem of how the spreading of diseases depends on structural patterns. Here, we contribute to further advance our underst...
We propose a generalized framework for the study of voter models in complex networks at the the heterogeneous mean-field (HMF) level that (i) yields a unified picture for existing copy/invasion proces...
A solution for the discretised version of some recently proposed kinetic exchange opinion dynamics models with two-agent interactions (Lallouache et. al.,Phys. Rev E 82, 056112 (2010)) is provided.A g...
We study the issues of scaling and universality in spectral and trans-port properties of the infinite dimensional particle–hole symmetric (half–filled) Hubbard model within dynamical mean field theory...
In the previous paper we have argued that the LHC data on multiplicity,average transverse momentum, and charged particle transverse momentum distributions are well described with minimal modeling in t...
A technique for measuring the mean impulse response function of stationary homogeneous isotropic turbulence is proposed. Such measurement is carried out here on the basis of Direct Numerical Simulati...
A new microscopic nucleon-nucleon (NN) interaction has been derived for the first time from the popular relativistic mean field theory (RMFT) Lagrangian. The NN interaction so obtained remarkably re...
