The paper explores in detail the intricate relationship between the results of the quantum-chemical calculations and the approximations they rely upon. When chemists want (or need) to include some ...

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 ...

A rotating cylinder with its side cut away to expose the core, showing patches of purple, blue, green, yellow, and orange that are dense in the middle and more diffuse toward the edges. This rotating ...

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, ...

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 ...

This paper is concerned with a striking visual experience: that of seeing geometric visual hallucinations. Hallucinatory images were classified by Klüver into four groups called form constants ...
