论文摘要
密度功能理论的表述是在熵推理的基础上构建的。该理论是作为热平衡中不均匀流体的最大熵的应用。结果表明，当施加了有关颗粒预期密度的信息时，熵推断会产生DFT的变异原理。此过程引入了一个试验密度聚标的密度矩阵，使用量子最大熵的方法从中发现了首选密度矩阵。作为插图，讨论了该理论的一些已知近似方案。
A formulation of the density functional theory is constructed on the foundations of entropic inference. The theory is introduced as an application of maximum entropy for inhomogeneous fluids in thermal equilibrium. It is shown that entropic inference produces the variational principle of DFT when information about the expected density of particles is imposed. This process introduces a family of trial density-parametrized density matrices from which the preferred density matrix is found using the method of quantum maximum entropy. As illustrations some known approximation schemes of the theory are discussed.
