Effective Spin Fluctuation Energies: How Should They Be Calculated? What Do They Mean?igh, the probability of the configuration appearing thermally is small, so finding the energy is the first step in understanding which are the most important configurations. Some of the questions which arise in the course of this computation are numerical in nature, and some conceptual. The numerica作者: eustachian-tube 時間: 2025-3-22 04:26

Spin Fluctuations and a Unified Picture of Magnetisme the modern theoretical research of magnetism has started with the advent of quantum mechanics. As is well known, in the major part of the modern theory of solids the mean-field approximation or the one-electron picture has been extremely successful.

Functional Integral Approach to the Low-Temperature Properties of Itinerant Ferromagnetseatments employ static or classical approximation. From the sense of this approximation, applicability of these theories ought to be restricted to the high-temperature properties.
