Local-density approximations (LDA) are a class of approximations to the exchange–correlation (XC) energy functional in density functional theory (DFT) that depend solely upon the value of the electronic density at each point in space (and not, for example, derivatives of the density or the Kohn–Sham orbitals). Many approaches can yield local approximations to the XC energy. However, overwhelmingly successful local approximations are those that have been derived fro… Web# สรุป1 เอาล่ะ ถึงแม้ว่า Chachiyo's Formula จะไม่ใช่ของวิเศษที่จะช่วยให้เราสร้างชุดไอรอนแมนหรือดาบไลท์เซเบอร์ได้ในวันนี้พรุ่งนี้ ...
