INTRODUCTION: Density functional theory (DFT) is a widely used method for calculating the electronic properties of materials. The method is based on the idea of approximating the many-electron wave ...

A review of previous attempts to test hypotheses derived from the functional theory of stratification suggests that to test the theory as formulated by Davis and Moore, the unit of analysis must be ...

In 1929, the physicist Paul Dirac wrote, “The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the ...

At its core, DFT postulates that the ground-state energy of a quantum system is a functional of the electron density. This principle, known as the Hohenberg-Kohn theorem, simplifies the problem of ...

Due to its high electron mobilities at ambient temperature and peculiar electronic behaviors like the quantum hall effect, which imitates massless transportation and results in high superconductivity, ...

As anyone who is familiar with personality trait theory knows, researchers have identified a “big five” of dispositional tendencies that reliably predict human behavioral patterns and show up almost ...

Density functional theory (DFT) is a widely used computational method for carrying out quantum calculations in chemistry, materials science, and biology research. Despite its enormous popularity and ...

Chemists use density functional theory (DFT) to accurately approximate the exact properties—like free energies—of molecules or materials in a reasonable amount of time. The method is widely used even ...

After a delay of nearly a week, the Florida Department of Education has released examples that it says backs up its rejection of dozens of math textbooks because they contained questions and exercises ...

Thinking about other people's thoughts recruits a specific group of brain regions, including the temporo-parietal junctions (TPJ), precuneus (PC), and medial prefrontal cortex (MPFC). The same brain ...
