Quantum Monte Carlo analysis of exchange and correlation in the strongly inhomogeneous electron gas.
We use the variational quantum Monte Carlo method to calculate the density-functional exchange-correlation hole n(xc), the exchange-correlation energy density e(xc), and the total exchange-correlation energy E(xc) of several strongly inhomogeneous electron gas systems. We compare our results with the local density approximation and the generalized gradient approximation. It is found that the no...
متن کاملEffects of Backflow Correlation in the Three-Dimensional Electron Gas: Quantum Monte Carlo Study
The correlation energy of the homogeneous three-dimensional interacting electron gas is calculated using the variational and fixed-node diffusion Monte Carlo methods, with trial functions that include backflow and three-body correlations. In the high density regime (rs ≤ 5) the effects of backflow dominate over those due to three-body correlations, but the relative importance of the latter incr...
متن کاملQuantum Monte Carlo Methods for Strongly Correlated Electron Systems
We review some of the recent development in quantumMonte Carlo (QMC) methods for models of strongly correlated electron systems. QMC is a promising general theoretical tool to study many-body systems, and has been widely applied in areas spanning condensed-matter, highenergy, and nuclear physics. Recent progress has included two new methods, the ground-state and finite-temperature constrained p...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
