tiheysfunktiotilan
Tiheysfunktiotila, often translated as density functional space, is a theoretical concept used in certain areas of computational physics and chemistry, particularly within the framework of density functional theory (DFT). It refers to the abstract space where the electron density of a system is considered the fundamental variable. In traditional quantum mechanics, the state of a system is described by a wavefunction, which depends on the coordinates of all electrons. DFT, however, posits that the ground-state energy and other properties of a system are uniquely determined by its electron density, a function of only three spatial coordinates. The tiheysfunktiotila is the domain of these electron density functions.
The core idea is that instead of solving the complex many-body Schrödinger equation involving the wavefunction,
