Madelung equations
WebSep 27, 2024 · The Madelung equations are two equations that are equivalent to the one-body time-dependent Schroedinger equation. In this paper, the Madelung equation, whose gradient is an Euler equation, is refined by introducing interpretations of functions that are shown to depend only on the real-part of the complex-valued wavefunction. WebFeb 28, 2024 · The Madelung constant M - named after Erwin Medelung - is a geometrical factor that depends on the arrangement of ions in the solid. For example, M for NaCl is a poorly converging series of interaction energies: M = 6 1 − 12 2 + 8 3 − 6 4 + 24 5... with Z is the number of charges of the ions, (e.g., 1 for NaCl ),
