Nonadditive hard-sphere fluid mixtures simple analytical theory Statistical Mechanics
font style='font-size:12px;'>
2011/8/18
Abstract: We construct a non-perturbative fully analytical approximation for the thermodynamics and the structure of non-additive hard-sphere fluid mixtures. The method essentially lies in a heuristic...
Prediction of the derivative discontinuity in density functional theory from an electrostatic description of the exchange and correlation potential
derivative discontinuity Prediction density functional theory electrostatic description correlation potential
font style='font-size:12px;'>
2011/8/5
Abstract: We propose a new approach to approximate the exchange and correlation (XC) functional in density functional theory. The XC potential is considered as an electrostatic potential, generated by...
